[46] 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. [27] 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. Yttrium is a silvery white, moderately soft, ductile metal. Yttrium Electrons per Shell 2,8,18,9,2 Atomic Number 39 Learn more about the atomic number. The most important uses of yttrium are LEDs and phosphors, particularly the red phosphors in television set cathode ray tube displays. Some people might just have known that it was one of 4 chemical elements named after the small Swedish town of Ytterby, along with ytterbium, erbium and terbium. 89Y is the only stable isotope, and the only isotope found in the Earth's crust. If you wish to use the Images in a manner not permitted by these terms and conditions please contact the Publishing Services Department by email. [19], Yttrium forms a water-insoluble fluoride, hydroxide, and oxalate, but its bromide, chloride, iodide, nitrate and sulfate are all soluble in water. Yttrium is a chemical element with the symbol Y and atomic number 39. The number of protons and electrons is the same. These are the valence electrons! Where more than one isotope exists, the value given is the abundance weighted average. The arrangements of electrons above the last (closed shell) noble gas. [77], A technique called radioembolization is used to treat hepatocellular carcinoma and liver metastasis. These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f). This is calculated by combining the scores for crustal abundance, reserve distribution, production concentration, substitutability, recycling rate and political stability scores. transition metal. Electron configuration Yttrium also finds use in fuel cells for powering cars and buses, computers and digital phones and, potentially, buildings. [6] 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. Exploring Chemical Elements and their Compounds. Y3(Fe,Al)5O12 and Y3(Fe,Ga)5O12) have important magnetic properties. This week, the last of the elements discovered in the small town of Ytterby and its compounds appear to have a multitude of uses. Y is the symbol for the element yttrium. Yttrium is an element that's symbol is Y and has the number 39. Then in 1986 two scientists working at IBM in Zurich, Georg Bednorz and Karl Müller, found that lanthanum barium copper oxide became superconducting at what was then almost a record high temperature, 35 degrees above absolute zero. [11], 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. The percentage of an element produced in the top producing country. This film can reach a thickness of 10 µm when yttrium is heated to 750 °C in water vapor. [7], Water-soluble compounds of yttrium are considered mildly toxic, while its insoluble compounds are non-toxic. [11] 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. B The nearest noble gas to yttrium is krypton, so yttrium is predicted to lose three electrons to form Y 3+, which has the same number of electrons as krypton. [56], Yttrium is used in small quantities in cathodes of some Lithium iron phosphate battery (LFP), and then called commonly LiFeYPO4 chemistry, or LYP. [48] In experiments on animals, yttrium and its compounds caused lung and liver damage, though toxicity varies with different yttrium compounds. However, the lanthanide rare earths contain elements of even atomic number and many stable isotopes. What is more, by introducing small quantities of lanthanide ions, materials with a range of useful properties can be made. [g][33][34][35], Friedrich Wöhler is credited with first isolating the metal in 1828 by reacting a volatile chloride that he believed to be yttrium chloride with potassium. Download our free Periodic Table app for mobile phones and tablets. Hence, the elements in a period have different chemical properties. This may not seem much of a temperature difference, but it meant that YBCO could be kept in the superconducting state using liquid nitrogen, rather than the much more expensive liquid helium. Isotopes Atomic weight of Yttrium is 88.90584 u or g/mol. One is that in order to superconduct at 95K, the YBCO has to be slightly oxygen-deficient, to have just a bit less than the seven oxygen atoms per yttrium atom. The electronegativity of Yttrium is: χ = 1.22. Yttrium's stable isotope is 89Y, which has 89 - 39 = 50 neutrons. That number is equal to the number of protons. Medium = substitution is possible but there may be an economic and/or performance impact, Low = substitution is possible with little or no economic and/or performance impact, If you wish to use the Images in a manner not permitted by these terms and conditions please contact the Publishing Services Department. At levels of 500 mg/m3, yttrium is immediately dangerous to life and health. Atomic Number of Yttrium Atomic Number of Yttrium is 39. It is defined as the equilibrium pressure exerted by the gas produced above a substance in a closed system. [7] 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. © 2009-2018 | www.prvky.com | kontaktkontakt [56] The single crystals of doped YAG are normally produced by the Czochralski process. 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). [60] When quaternary ammonium salts are used as extractants, most yttrium will remain in the aqueous phase. Values are given for typical oxidation number and coordination. Electronegativity (Pauling scale)The tendency of an atom to attract electrons towards itself, expressed on a relative scale. What is known is that the composition of the copper-oxide materials must be precisely controlled for superconductivity to occur. When the counter-ion is nitrate, the light lanthanides are removed, and when the counter-ion is thiocyanate, the heavy lanthanides are removed. Chemistry in its element is brought to you by the Royal Society of Chemistry and produced by. [84] Yttrium dust is highly flammable. Electron configuration The arrangements of electrons above the last (closed shell) noble gas. It is quite stable in air; rapid oxidation begins above approximately 450 °C (840 °F), resulting in Y2O3. The ultimate objective, the Holy Grail, is to find a material that would superconduct at room temperature, but no one has got there yet. The theory of low temperature superconductivity has been well understood since the BCS theory of 1957.

Elements are organised into blocks by the orbital type in which the outer electrons are found. The temperature at which the liquid–gas phase change occurs. If you are in any doubt, please ask. [43], In 1987, yttrium barium copper oxide was found to achieve high-temperature superconductivity. The Chemical Abstracts Service registry number is a unique identifier of a particular chemical, designed to prevent confusion arising from different languages and naming systems. A horizontal row in the periodic table. Members of a group typically have similar properties and electron configurations in their outer shell. Some elements exist in several different structural forms, called allotropes. Melting point It’s Elemental - The Periodic Table of Elements. It is given by the ratio of the shear stress to the shear strain. [26], Yttrium isotopes are among the most common products of the nuclear fission of uranium in nuclear explosions and nuclear reactors. B Y has more electrons in its outer shell than X. ●Number of protons in Yttrium(Y) is 39.Protons are present in the nucleus of Yttrium(Y). [27] Isotopes with mass numbers at or above 97 are also known to have minor decay paths of β− delayed neutron emission. Yttrium atoms have 39 electrons and the shell structure is 2.8.18.9.2. The description of the element in its natural form. Each entry has a full citation identifying its source. 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. It is a silver metallic transition metal that has properties similar to lanthanoids and is a rare earth mineral. [h], Yttrium is found in most rare-earth minerals,[9] it is found in some uranium ores, but is never found in the Earth's crust as a free element. These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f). The role of the element in humans, animals and plants. "This REY-rich mud has great potential as a rare-earth metal resource because of the enormous amount available and its advantageous mineralogical features," the study reads. Yttrium aluminium garnet, also known as YAG, is a very important synthetic mineral. In 1794, Gadolin announced that it contained a new 'earth' which made up 38 per cent of its weight. The percentage of a commodity which is recycled. The value of ml determines the number of orbitals in a subshell. Such materials are used in the "cool white" fluorescent lamps. [12] 89Y has a mass number close to 90 and has 50 neutrons in its nucleus. C Y is in a different group of the Periodic Table from X. The mine had been developed in the early 18th century as a result of the mineral requirements of the local pottery industry. This is approximately the sum of the number of protons and neutrons in the nucleus. Similar to LFP, LYP batteries offer high energy density, good safety and long life. [39][40] A fourth oxide, ytterbium oxide, was isolated in 1878 by Jean Charles Galissard de Marignac. Comprehensive data on the chemical element Yttrium is provided on this page; including scores of properties, element names in many languages, most known nuclides of Yttrium.

Melting point of Yttrium is 1523 °C and its the boiling point is 3337 °C. Investigators are looking into depositing YBCO on top of flexible metal wires, and research into this continues. These values were determined using several different methods. Our yttrium page has over 200 facts that span 92 different quantities. 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. In 1843, Carl Mosander investigated yttrium oxide more thoroughly and found that it consisted of three oxides: yttrium oxide, which was white; terbium oxide, which was yellow; and erbium oxide, which was rose-coloured. Its soluble salts are mildly toxic. [20] Vaporization of the graphite intercalation compounds graphite–Y or graphite–Y2O3 leads to the formation of endohedral fullerenes such as Y@C82. The s-process is a slow neutron capture of lighter elements inside pulsating red giant stars. Areas covered include atomic structure, physical properties, atomic interaction, thermodynamics, identification, atomic size, crystal structure, history, abundances, and nomenclature. The metal readily reacts with diluted Welcome to "A Visual Interpretation of The Table of Elements", the most striking version of the periodic table on the web. [61] Only a few tonnes of yttrium metal are produced each year by reducing yttrium fluoride to a metal sponge with calcium magnesium alloy. [12] 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 mass of an atom relative to that of carbon-12. [15], It often also falls in the same range for reaction order,[11] resembling terbium and dysprosium in its chemical reactivity.

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. [68] Yttrium aluminium garnet (Y3Al5O12 or YAG) has a hardness of 8.5 and is also used as a gemstone in jewelry (simulated diamond). Johan Gadolin, named by Anders Gustaf Ekeberg. Please enable JavaScript to access the full features of the site. Boiling point: 6,053 F (3,345 C) 6. Bengt Geijer, the inspector of mines in Stockholm, carried out a rough analysis of ytterbite. Yttrium oxide is added to the glass used to make camera lenses to make them heat and shock resistant. Electron emission of isotopes with those mass numbers is simply less prevalent due to this stability, resulting in them having a higher abundance. Now, whilst no reputable scientist would argue that a magnetic monopole could open an inter-dimensional portal, its existence isn't outside the realms of possibility and if recent reports are anything to go by, it could depend on an otherwise mundane metallic element that you can find skulking around near the bottom of the Periodic Table - holmium. The higher the associated electronegativity number, the more an element or compound attracts electrons … Yttrium (Y), chemical element, a rare-earth metal of Group 3 of the periodic table. State at room temperature: Solid The transition of a substance directly from the solid to the gas phase without passing through a liquid phase. Yttrium atoms have 39 electrons and the shell structure is 2.8.18.9.2. Anion Y - has one more electron than its neutral atom. This is where the artist explains his interpretation of the element and the science behind the picture. There are three electrons outside of the noble gas core. [11], Organoyttrium chemistry is the study of compounds containing carbon–yttrium bonds. Electrons per shell. [6] Electron spin resonance studies indicated the formation of Y3+ and (C82)3− ion pairs. [46] Lunar rock samples collected during the American Apollo Project have a relatively high content of yttrium. The story of yttrium’s discovery begins in 1787, when Carl Arrhenius found a coal-like mineral in a feldspar/quartz mine near Ytterby, Sweden. 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. [44] This superconductor is notable because the operating superconductivity temperature is above liquid nitrogen's boiling point (77.1 K). The number of protons is equal to the number of electrons, unless there’s an ion superscript listed after the element. [48] 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). Yttrium oxide and iron oxide combine … Images © Murray Robertson 1999-2011 Click on 'Element Atomic Number', 'Element Symbol', 'Element Name' and 'Element Valence Electrons' headers to sort. Y atom has 17 electrons and therefore, in Y -,number of electrons will be 18 (17 + 1). Copyright of and ownership in the Images reside with Murray Robertson. [2][20] (The +2 state has been observed in chloride melts,[21] and +1 in oxide clusters in the gas phase. 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. 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. The Kossel shell structure of yttrium. [11], Water readily reacts with yttrium and its compounds to form Y2O3. That has the unusual property of conducting oxide ions, making it very useful in these fuel cells. By reacting the resulting yttrium oxide with hydrogen fluoride, yttrium fluoride is obtained. 1. If there are more electrons than protons, the ion has a negative charge and is called an anion. "Element 39: Yttrium". [11], Yttrium in the Solar System was created through stellar nucleosynthesis, mostly by the s-process (≈72%), but also by the r-process (≈28%). First ionisation energyThe minimum energy required to remove an electron from a neutral atom in its ground state. The electrons in the outermost shell of an atom are called: valence electrons The valence electrons of an atom are those in the outermost shell, which are available for bonding or ionization. Yttrium is often used as an additive in alloys. The chemical symbol for Yttrium is Y. [8] Scandium has one stable isotope, and yttrium itself has only one stable isotope, 89Y, which is also the only isotope that occurs naturally. The red component of color television cathode ray tubes is typically emitted from a yttria (Y2O3) or yttrium oxide sulfide (Y2O2S) host lattice doped with europium (III) cation (Eu3+) phosphors. Singular. This Site has been carefully prepared for your visit, and we ask you to honour and agree to the following terms and conditions when using this Site. Yttrium Y Element 39 Mass Number: 89 Atomic weight: 88.905 g/mol Atomic number (Z): 39 Electrons: 39 Protons: 39 Neutrons: 50 Period: 5 Group: 3 Block: d [11] The Y3+ ion is colorless in solution because of the absence of electrons in the d and f electron shells. It provides a measure of how difficult it is to extend a material, with a value given by the ratio of tensile strength to tensile strain. Block Elements are organised into blocks by the orbital type in which the outer electrons are found. Density is the mass of a substance that would fill 1 cm3 at room temperature. A small amount of yttrium oxide is added to zirconium oxide to make what is known as yttria-stabilized zirconia (also called YSZ). Y. [7], There is disagreement in the literature whether lanthanum (La) or, Metastable isomers have higher-than-normal energy states than the corresponding non-excited nucleus and these states last until a. Earths were given an -a ending and new elements are normally given an -ium ending. [26][c] This stability is thought to result from their very low neutron-capture cross-section. In such cases we would ask you to sign a Visual Elements licence agreement, tailored to the specific use you propose. Chemical symbol for Yttrium is Y. And erbium gives you an infrared laser. If the periodic table is complete just scroll up and read the number on the top (from 1 to 18). Half of the distance between two unbonded atoms of the same element when the electrostatic forces are balanced. [13] Chemically, yttrium resembles those elements more closely than its neighbor in the periodic table, scandium,[14] 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. [29], Until the early 1920s, the chemical symbol Yt was used for the element, after which Y came into common use. [6] The carbides Y3C, Y2C, and YC2 can be hydrolyzed to form hydrocarbons. 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. Uncombined elements have an oxidation state of 0. It is based on a peculiarity of the interaction between two electrons in a crystal lattice. With the addition of oxalic acid, the yttrium oxalate precipitates. It has the formulaYBa. Electrons have a specific form of distribution (or configuration) in every atom, even Yttrium. Yttrium metal of 99.9% purity is commercially available at a cost of about $75/oz.

[27], Yttrium isotopes with mass numbers at or below 88 decay primarily by positron emission (proton → neutron) to form strontium (Z = 38) isotopes. Finland Atomic weight. pp. [26][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's atomic number is 39. [62], Yttrium can be used to deoxidize vanadium and other non-ferrous metals. Low = substitution is possible with little or no economic and/or performance impact. [41] 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). The radioactive isotope yttrium-90 has medical uses. Yttrium-aluminium garnet (YAG) is used in lasers that can cut through metals. [6], Yttrium is used in the production of a large variety of synthetic garnets,[66] and yttria is used to make yttrium iron garnets (Y3Fe5O12, also "YIG"), which are very effective microwave filters[12] which were recently shown to have magnetic interactions more complex and longer-ranged than understood over the previous four decades. [12] Yttrium nitride (YN) is formed when the metal is heated to 1000 °C in nitrogen. [25] The r-process consists of rapid neutron capture by lighter elements during supernova explosions. We welcome your feedback.
