Atomic symbol (on Periodic Table of Elements): Y 3. Mira is a type of giant red star where most of the yttrium is concentrated in the solar system. Needles made of yttrium-90, which can cut more precisely than scalpels, have been used to sever pain-transmitting nerves in the spinal cord, and yttrium-90 is also used to carry out radionuclide synovectomy in the treatment of inflamed joints, especially knees, in sufferers of conditions such as rheumatoid arthritis.  Yttrium nitride (YN) is formed when the metal is heated to 1000 °C in nitrogen.  This superconductor is notable because the operating superconductivity temperature is above liquid nitrogen's boiling point (77.1 K).  Isotopes with mass numbers at or above 97 are also known to have minor decay paths of β− delayed neutron emission. Each entry has a full citation identifying its source. In its elemental form, CAS 7440-65-5, Yttrium has a silvery white appearance.  Lunar rock samples collected during the American Apollo Project have a relatively high content of yttrium. , Yttrium has at least 20 metastable ("excited") isomers ranging in mass number from 78 to 102. Follow the appropriate hyperlinks for definitions of each radius type. Small amounts of yttrium (0.1 to 0.2%) can be used to reduce the grain size in chromium, molybdenum, zirconium, and titanium, and to increase strength of aluminum and magnesium alloys. Yttrium and Terbium, Dysprosium, Holmium, Erbium, Thulium, Ytterbium and Lutetium adds up to total Heavy Rare Earth Metals market. It is not always easy to make sensible comparisons between the elements however as some bonds are quite short because of multiple bonding (for instance the O=O distance in O2 is short because of the the double bond connecting the two atoms.  Though 90Y has a short half-life, it exists in secular equilibrium with its long-lived parent isotope, strontium-90 (90Sr) with a half-life of 29 years.. This page was last edited on 2 December 2020, at 20:31. Melting point: 2,772 Fahrenheit (1,522 Celsius) 5. , Yttrium isotopes are among the most common products of the nuclear fission of uranium in nuclear explosions and nuclear reactors. "Element 39: Yttrium".  89Y has a mass number close to 90 and has 50 neutrons in its nucleus. ~Small amounts of yttrium (0.1 to 0.2%) can be used to reduce the grain size in chromium, molybdenum, zirconium, and titanium, and to increase strength of aluminum and magnesium alloys. ) Some trimerization reactions were generated with organoyttrium compounds as catalysts.  Cerium-doped yttrium aluminium garnet (YAG:Ce) crystals are used as phosphors to make white LEDs. , A technique called radioembolization is used to treat hepatocellular carcinoma and liver metastasis.  Since yttria was found to be a mineral and not an oxide, Martin Heinrich Klaproth renamed it gadolinite in honor of Gadolin. A great tool for educators.  Yttrium dust is highly flammable. , As of April 2018[update] there are reports of the discovery of very large reserves of rare-earth elements on a tiny Japanese island.  Electron spin resonance studies indicated the formation of Y3+ and (C82)3− ion pairs. For definitions of ionic radius and further information, follow the hypertext link. Nausea 15.  Scandium has one stable isotope, and yttrium itself has only one stable isotope, 89Y, which is also the only isotope that occurs naturally. 90 Y has been used for downstaged HCC and, in recent studies, has outperformed TACE. Yttrium is a kind of metal. The name is historical and comes from the village of Ytterby, in Sweden where, in 1787, the chemist Arrhenius found a new mineral and named it ytterbite. , Yttrium forms a water-insoluble fluoride, hydroxide, and oxalate, but its bromide, chloride, iodide, nitrate and sulfate are all soluble in water. In the usual situation, where yttrium is in a mixture that is two-thirds heavy-lanthanide, yttrium should be removed as soon as possible to facilitate the separation of the remaining elements.  When quaternary ammonium salts are used as extractants, most yttrium will remain in the aqueous phase. A Stuffy And Runny Nose 3. 12–13). sizeof is a unary operator in the programming languages C and C++.It generates the storage size of an expression or a data type, measured in the number of char-sized units.Consequently, the construct sizeof (char) is guaranteed to be 1.The actual number of bits of type char is specified by the preprocessor macro CHAR_BIT, defined in the standard include file limits.h.  Having a high melting point, yttrium oxide is used in some ceramic and glass to impart shock resistance and low thermal expansion properties. One method for obtaining pure yttrium from the mixed oxide ores is to dissolve the oxide in sulfuric acid and fractionate it by ion exchange chromatography. , Yttrium is used in the production of a large variety of synthetic garnets, and yttria is used to make yttrium iron garnets (Y3Fe5O12, also "YIG"), which are very effective microwave filters which were recently shown to have magnetic interactions more complex and longer-ranged than understood over the previous four decades. x + y = 0 y + z = 3 z – x = 2. A Skin Rash 2. Anemia 3. Researchers are studying a class of materials known as perovskites that are alternative combinations of these elements, hoping to develop a practical high-temperature superconductor.  Normally, as little as 0.5 milligrams is found in the entire human body; human breast milk contains 4 ppm. An Infection 2.  When finely divided, however, yttrium is very unstable in air; shavings or turnings of the metal can ignite in air at temperatures exceeding 400 °C. Annual world production of yttrium oxide had reached 600 tonnes by 2001; by 2014 it had increased to 7,000 tons. This site yielded several unusual minerals containing rare earths and other elements. The s-process is a slow neutron capture of lighter elements inside pulsating red giant stars.  The Occupational Safety and Health Administration (OSHA) limits exposure to yttrium in the workplace to 1 mg/m3 over an 8-hour workday. Exposure to yttrium compounds can cause lung disease in humans..  As a metal, yttrium is used on the electrodes of some high-performance spark plugs. In 2013, China's yttrium mine production amounted to approximately 7,000 metric tons of yttrium-oxide. As such yttrium compounds such as yttrium aluminium garnet (YAG) are useful for phosphors and are an important component of white LEDs. ~Yttrium aluminum garnet, with a hardness of 8.5, is also finding use as a gemstone (simulated diamond). Save 50% off a Britannica Premium subscription and gain access to exclusive content. Yttrium is a soft, silver transition metal. As expected by periodic trends, it is less electronegative than its predecessor in the group, scandium, and less electronegative than the next member of period 5, zirconium; additionally, it is more electronegative than lanthanum, but less electronegative than lutetium due to the lanthanide contraction. Decreased Appetite 7.  Yttrium, iron, aluminium, and gadolinium garnets (e.g. Yttria (Y), an earth containing yttrium was discovered in 1794 by Gadolin. , Hapticity is a term to describe the coordination of a group of contiguous atoms of a ligand bound to the central atom; it is indicated by the Greek character eta, η. Yttrium complexes were the first examples of complexes where carboranyl ligands were bound to a d0-metal center through a η7-hapticity. 150–152. Geographies of this market are North America, Asia-Pacific, Europe and South America, Africa, Middle East. Yttrium chemical symbol is Y, atomic number is 39 and its atomic weight is 88.9 g/mol. Sources, facts, uses, scarcity (SRI), podcasts, alchemical symbols, videos and images. Ion absorption clays or Lognan clays are the weathering products of granite and contain only 1% of REEs. Conversion factors are: The size of neutral atoms depends upon the way in which the measurement is made and the environment. Yttria is used as a sintering additive in the production of porous silicon nitride. The other three elements are erbium, terbium, and ytterbium. Our yttrium page has over 200 facts that span 92 different quantities. Is Greenland really as big as all of Africa? This statistic depicts the global production of yttrium from 2010 to 2013, by country. , In 1843, Carl Gustaf Mosander found that samples of yttria contained three oxides: white yttrium oxide (yttria), yellow terbium oxide (confusingly, this was called 'erbia' at the time) and rose-colored erbium oxide (called 'terbia' at the time). Cough 6.  Chemically, yttrium resembles those elements more closely than its neighbor in the periodic table, scandium, and if physical properties were plotted against atomic number, it would have an apparent number of 64.5 to 67.5, placing it between the lanthanides gadolinium and erbium. We have found that height is a better indicator of size than weight. Yttrium is used as a deoxidizer for vanadium and other nonferrous metals. Alloys with other useful properties can be obtained by using yttrium as an additive. Exploring Chemical Elements and their Compounds. Yttrium is one of four elements named for the same small town of Ytterby, Sweden.  (The +2 state has been observed in chloride melts, and +1 in oxide clusters in the gas phase. It was found in a quarry located at Ytterby in Sweden. Intense Abdominal Pain 12. Diarrhea 8. This sample represents yttrium in the "The Grand Tour of the Periodic Table" mineral collection from Jensan Scientifics.  YIG is also very efficient as an acoustic energy transmitter and transducer. , A neodymium-doped yttrium-aluminium-garnet laser has been used in an experimental, robot-assisted radical prostatectomy in canines in an attempt to reduce collateral nerve and tissue damage, and erbium-doped lasers are coming into use for cosmetic skin resurfacing.. At levels of 500 mg/m3, yttrium is immediately dangerous to life and health. 3.4.8 A [ 21, 31 ].  Yttrium is also used in the production of electrodes, electrolytes, electronic filters, lasers, superconductors, various medical applications, and tracing various materials to enhance their properties. The pure element is relatively stable in air in bulk form, due to passivation of a protective oxide (Y2O3) film that forms on the surface. , The similarities of yttrium to the lanthanides are so strong that the element has historically been grouped with them as a rare-earth element, and is always found in nature together with them in rare-earth minerals. Mosander showed that yttria contained the earths of three elements in 1843.  In experiments on animals, yttrium and its compounds caused lung and liver damage, though toxicity varies with different yttrium compounds. It is a silvery-metallic transition metal chemically similar to the lanthanides and has often been classified as a "rare-earth element". In this table, geometry refers to the arrangment of the ion's nearest neighbours. The study shows that more than 16 million tons of rare-earth elements could be "exploited in the near future." The names yttria was given to the most basic, while the other two became erbia and terbia. Generalized Weakness 11. Yttrium is a soft, silver-metallic, lustrous and highly crystalline transition metal in group 3. Density: 4.47 grams per cubic centimeter 7. , Yttrium is used in small quantities in cathodes of some Lithium iron phosphate battery (LFP), and then called commonly LiFeYPO4 chemistry, or LYP.  Global reserves of yttrium oxide were estimated in 2014 to be more than 500,000 tons.  Concentrated nitric and hydrofluoric acids do not rapidly attack yttrium, but other strong acids do. The discovery of yttrium marked the beginning of one hundred years of complicated chemical research that resulted in the discovery often new elements. Bleeding 4. In this way, yttrium salts of 99.999% purity are obtained. The metal can be used as a deoxidizer for vanadium and other nonferrous metals. , Yttrium isotopes with mass numbers at or below 88 decay primarily by positron emission (proton → neutron) to form strontium (Z = 38) isotopes.  A fourth oxide, ytterbium oxide, was isolated in 1878 by Jean Charles Galissard de Marignac. Element Yttrium (Y), Group 3, Atomic Number 39, d-block, Mass 88.906. The bond length in YY is: 355.1pm. , Yttrium has been studied as a nodulizer in ductile cast iron, forming the graphite into compact nodules instead of flakes to increase ductility and fatigue resistance.  With as much as 700 ppm, the seeds of woody plants have the highest known concentrations. Heiserman, David L. (1992). I first need to rearrange the system as: x + y = 0 y + z = 3 –x + z = 2 Then I can write the associated matrix as: When forming the augmented matrix, use a zero for any entry where the corresponding spot in the system of linear equations is blank. The ferroelectric properties of yttrium-doped hafnia films prepared by CSD do not significantly vary under a thickness change from 29 to 66 nm, as illustrated in Fig. Objective: Yttrium-90 radioembolization is an emerging treatment for liver malignancies. It is based on a peculiarity of the interaction between two electrons in a crystal lattice. [c] This stability is thought to result from their very low neutron-capture cross-section. With the addition of oxalic acid, the yttrium oxalate precipitates. The temperature of an arc furnace of greater than 1,600 °C is sufficient to melt the yttrium.. The periodic t…  Similarly, carbon, phosphorus, selenium, silicon and sulfur all form binary compounds with yttrium at elevated temperatures. 1. Copyright 1993-2020 Mark Winter [ The University of Sheffield and WebElements Ltd, UK]. Minami-Torishima Island, also known as Marcus Island, is described as having "tremendous potential" for rare-earth elements and yttrium (REY), according to a study published in Scientific Reports. Yttrium aluminum garnets, with a hardness of 8.5, are used to simulate diamond gemstones. The term "atomic radius" is not particularly helpful although its use is widespread. In medicine, yttrium 90 is used to help kill cancer cells. One measure of size is the element-element distance within the element. Size does depend upon geometry and environment.  It works by adhering to monoclonal antibodies, which in turn bind to cancer cells and kill them via intense β-radiation from the yttrium-90 (see monoclonal antibody therapy). Low Levels Of A Type Of White Blood Cell Called Neutrophils If experienced, these tend to have a Less Severe expression 1. In rats, inhalation of yttrium citrate caused pulmonary edema and dyspnea, while inhalation of yttrium chloride caused liver edema, pleural effusions, and pulmonary hyperemia. Alloys with other useful properties can be obtained by using yttrium as an additive.  The addition of yttrium to alloys generally improves workability, adds resistance to high-temperature recrystallization, and significantly enhances resistance to high-temperature oxidation (see graphite nodule discussion below). The problem is its meaning, which is clearly very different in different sources and books.

Apart from the isotopes 91Y, 87Y, and 90Y, with half-lives of 58.51 days, 79.8 hours, and 64 hours, respectively, all the other isotopes have half-lives of less than a day and most of less than an hour. , It often also falls in the same range for reaction order, resembling terbium and dysprosium in its chemical reactivity. A follow-up study may demonstrate continued decrease in size and enhancement without additional therapy (Figure 9-17). At least 32 synthetic isotopes of yttrium have been observed, and these range in atomic mass number from 76 to 108. Yttrium is a transition metal. WebElements: THE periodic table on the WWW [www.webelements.com] When the counter-ion is nitrate, the light lanthanides are removed, and when the counter-ion is thiocyanate, the heavy lanthanides are removed. , Yttrium has no known biological role, though it is found in most, if not all, organisms and tends to concentrate in the liver, kidney, spleen, lungs, and bones of humans. Yttrium and all lanthanides except Ce and Pm have been observed in the oxidation state 0 in bis(1,3,5-tri-t-butylbenzene) complexes, see, The electronegativity of both scandium and yttrium are between. Electron emission of isotopes with those mass numbers is simply less prevalent due to this stability, resulting in them having a higher abundance. A slight distinction is recognized between the light (LREE) and the heavy rare-earth elements (HREE), but the distinction is not perfect. The yttrium atom has a radius of 177.6.pm and its Van der Waals radius is 200.pm. Bronchitis 4. Used in production of synthetic garments and yttrium iron garments. Throat Irritation Since yttrium-90 is a synthetic isotope and has circumscribed uses, releases to the environment of yttrium-90 would be very limited. This statistic displays a forecast of the price development of rare earth oxide yttrium oxide globally from 2009 to 2025. , Since yttrium is chemically so similar to the lanthanides, it occurs in the same ores (rare-earth minerals) and is extracted by the same refinement processes. Yttrium is a chemical element in the periodic table with atomic number 39, discovered by Johan Gadolin in the year 1794. Its density at room temperature is 4.472g/cm3.  Yttrium isotopes with mass numbers at or above 90 decay primarily by electron emission (neutron → proton) to form zirconium (Z = 40) isotopes. The reason for this is still not clear, but it is known that the vacancies occur only in certain places in the crystal, the copper oxide planes, and chains, giving rise to a peculiar oxidation state of the copper atoms, which somehow leads to the superconducting behavior. Including yttrium (Y), which is used in products like camera lenses and mobile phone screens, the rare-earth elements found are europium (Eu), terbium (Tb), and dysprosium (Dy).  While most of yttrium's isomers are expected to be less stable than their ground state, 78mY, 84mY, 85mY, 96mY, 98m1Y, 100mY, and 102mY have longer half-lives than their ground states, as these isomers decay by beta decay rather than isomeric transition. About Yttrium; Yttrium weighs 4.469 gram per cubic centimeter or 4 469 kilogram per cubic meter, i.e. Small amounts of yttrium (0.1 to 0.2%) can be used to reduce the grain size in chromium, molybdenum, zirconium, and titanium, and to increase strength of aluminum and magnesium alloys. ". Similar to LFP, LYP batteries offer high energy density, good safety and long life. Boiling point: 6,053 F (3,345 C) 6.  Major manufacturer of LFP batteries is Shenzhen Smart Lion Power Battery Limited, with brands Winston and Thunder Sky.. [f] Anders Gustaf Ekeberg confirmed the identification in 1797 and named the new oxide yttria. China is the world's largest producer and consumer of yttrium products. , Water-soluble compounds of yttrium are considered mildly toxic, while its insoluble compounds are non-toxic. , The radioactive isotope yttrium-90 is used in drugs such as Yttrium Y 90-DOTA-tyr3-octreotide and Yttrium Y 90 ibritumomab tiuxetan for the treatment of various cancers, including lymphoma, leukemia, liver, ovarian, colorectal, pancreatic and bone cancers. The metal can be used as a deoxidizer for vanadium and other nonferrous metals.  Workers exposed to airborne yttrium europium vanadate dust experienced mild eye, skin, and upper respiratory tract irritation—though this may be caused by the vanadium content rather than the yttrium.  Vaporization of the graphite intercalation compounds graphite–Y or graphite–Y2O3 leads to the formation of endohedral fullerenes such as Y@C82. Follow the appropriate hyperlinks for literature references and definitions of each type of radius. , Johan Gadolin at the University of Åbo identified a new oxide (or "earth") in Arrhenius' sample in 1789, and published his completed analysis in 1794.  Acute exposure to yttrium compounds can cause shortness of breath, coughing, chest pain, and cyanosis.  Even though the lanthanides are one row farther down the periodic table than yttrium, the similarity in atomic radius may be attributed to the lanthanide contraction. It has high melting point, about 1526oC and boiling point is 2903oC. Yttrium is concentrated in the HREE group because of its ion size, though it has a lower atomic mass. For example, size(A,[2 3]) returns the lengths of the second and third dimensions of A in the 1-by-2 row vector szdim.  Yttrium is so close in size to the so-called 'yttrium group' of heavy lanthanide ions that in solution, it behaves as if it were one of them. Stable yttrium-89 is the only naturally occurring isotope. , YAG, yttria, yttrium lithium fluoride (LiYF4), and yttrium orthovanadate (YVO4) are used in combination with dopants such as neodymium, erbium, ytterbium in near-infrared lasers. Yttrium is the first d-block element in the fifth period.  About 31 ppm of the Earth's crust is yttrium, making it the 28th most abundant element, 400 times more common than silver.  These syntheses use YCl3 as a starting material, obtained from Y2O3 and concentrated hydrochloric acid and ammonium chloride. Also see radioembolization in the case of combined cirrhosis and hepatocellular carcinoma.  The carbides Y3C, Y2C, and YC2 can be hydrolyzed to form hydrocarbons. Yttrium currently has no known biological role, and it can be highly toxic to humans, animals and plants. You can reference the WebElements periodic table as follows:"WebElements, https://www.webelements.com, accessed December 2020. Atomic number (number of protons in the nucleus): 38 2.  The single crystals of doped YAG are normally produced by the Czochralski process. All group 3 elements have an odd atomic number, and therefore few stable isotopes.  Yttrium aluminium garnet (Y3Al5O12 or YAG) has a hardness of 8.5 and is also used as a gemstone in jewelry (simulated diamond). Element 39 of Periodic table is Yttrium with atomic number 39, atomic weight 88.90585. , In 1987, yttrium barium copper oxide was found to achieve high-temperature superconductivity. State at room temperature: Solid Transition metals are those elements in Groups 3 through 12 of the periodic table. The bond length in YY is: 355.1pm. It is minimally invasive and patients can usually be discharged after a few hours. There are several other ways ways to define radius for atoms and ions. , Yttrium can be used to deoxidize vanadium and other non-ferrous metals.  Since liquid nitrogen is less expensive than the liquid helium required for metallic superconductors, the operating costs for applications would be less. [b] Such a slow process tends to favor isotopes with atomic mass numbers (A = protons + neutrons) around 90, 138 and 208, which have unusually stable atomic nuclei with 50, 82, and 126 neutrons, respectively. Yttrium-89 is thought to be more abundant than it otherwise would be, due in part to the s-process, which allows enough time for isotopes created by other processes to decay by electron emission (neutron → proton). All rights reserved. Size: 1" Composition: Y Ba 2 Cu 3 O 7: Allanite from Jensan Set. A total of 33 (excluding nuclear isomers) radioactive isotopes of yttrium ranging in mass from 77 to 109 and half-life from 41 milliseconds (yttrium-108) to 106.63 days (yttrium-88) have been reported.  Yttrium is found in soil in concentrations between 10 and 150 ppm (dry weight average of 23 ppm) and in sea water at 9 ppt.  It was only the second material known to exhibit this property, and it was the first known material to achieve superconductivity above the (economically important) boiling point of nitrogen.  New elements were later isolated from each of those oxides, and each element was named, in some fashion, after Ytterby, the village near the quarry where they were found (see ytterbium, terbium, and erbium). LYP cells have essentially same nominal voltage as LFP, of 3.25V, and very similar charging and discharge characteristic. , This superconductor is a black and green, multi-crystal, multi-phase mineral.  Yttrium is used in gas mantles for propane lanterns as a replacement for thorium, which is radioactive. Small quantities of yttrium may be added to reduce the grain size in chromium, molybdenum, zirconium, and titanium, and to increase the strength of aluminum and magnesium alloys. Yttrium can be segmented by Geographies, Applications and Companies. pp. , In 1787, part-time chemist Carl Axel Arrhenius found a heavy black rock in an old quarry near the Swedish village of Ytterby (now part of the Stockholm Archipelago). Alloys with other useful properties can be obtained by using yttrium as an additive. Dizziness 9. A few of these are known to have yttrium in the oxidation state 0.  The r-process consists of rapid neutron capture by lighter elements during supernova explosions. Starting in R2019b, you can also specify dim as a vector of positive integers to query multiple dimension lengths at a time. , Organoyttrium chemistry is the study of compounds containing carbon–yttrium bonds. This characteristic is the basis for many of its applications. Yttrium is a key ingredient in the yttrium barium copper oxide (YBa2Cu3O7, aka 'YBCO' or '1-2-3') superconductor developed at the University of Alabama and the University of Houston in 1987. The radioactive microspheres are delivered directly to the blood vessels feeding specific liver tumors/segments or lobes.  In the decades after Antoine Lavoisier developed the first modern definition of chemical elements, it was believed that earths could be reduced to their elements, meaning that the discovery of a new earth was equivalent to the discovery of the element within, which in this case would have been yttrium. Two values are given here, one is based upon calculations and the other upon observation - follow the appropriate link for further details.  The Y3+ ion is colorless in solution because of the absence of electrons in the d and f electron shells. , Currently under development is yttrium-stabilized zirconia as a solid electrolyte and as an oxygen sensor in automobile exhaust systems.  Yttrium is used to increase the strength of aluminium and magnesium alloys. Due to the presence of a large number of reserves of the rare earth metal, the country is also a key producer of yttrium metal and yttrium oxide. Follow the appropriate hyperlinks for literature references and definitions of each type of radius. szdim = size(A,dim) returns the length of dimension dim when dim is a positive integer scalar. The Rmax values for neutral gaseous element valence orbitals are abstracted from reference 1. Y3(Fe,Al)5O12 and Y3(Fe,Ga)5O12) have important magnetic properties. The oxalate is converted into the oxide by heating under oxygen. As expected by periodic trends, it is less electronegative than its predecessor in the group, scandium, and less electronegative than the next member of period 5, zirconium; additionally, it is more electronegative than lanthanum, but less electronegative than lutetium due to the lanthanide contraction. , As a trivalent transition metal, yttrium forms various inorganic compounds, generally in the oxidation state of +3, by giving up all three of its valence electrons. , Exposure to yttrium compounds in humans may cause lung disease. The actual superconducting material is often written as YBa2Cu3O7–d, where d must be less than 0.7 for superconductivity. This table gives some ionic radii. Yttrium is a chemical element with the symbol Y and atomic number 39. In 2009, Professor Mas Subramanian and associates at Oregon State University discovered that yttrium can be combined with indium and manganese to form an intensely blue, non-toxic, inert, fade-resistant pigment, YInMn blue, the first new blue pigment discovered in 200 years. , With halogens, yttrium forms trihalides such as yttrium(III) fluoride (YF3), yttrium(III) chloride (YCl3), and yttrium(III) bromide (YBr3) at temperatures above roughly 200 °C. The terms low spin and high spin refer to the electronic configurations of particular geomtries of certain d-block metal ions. , Small amounts of yttrium (0.1 to 0.2%) have been used to reduce the grain sizes of chromium, molybdenum, titanium, and zirconium.  Those same properties make such glass useful in camera lenses. The town is responsible for the names erbium, terbium and ytterbium.
