Russia) "Yttrium." The element was named after the Swedish village of Ytterby, where it was mined. Yttrium-aluminium garnet (Y3Al5O12) is used in lasers that can cut through metals, It is also used in white LED lights. 90Yttrium, a radioactive isotope, is used in treatments for various cancers and is used in precision medical needles to sever pain-transmitting nerves in the spinal cord. Isotopes:  87Y 88Y 89Y 90Y 91Y, The metal tarnishes slowly in air and burns readily, forming: A low resistivity indicates a material that readily allows the flow of electric current.

Biological role:  Its soluble salts are mildly toxic. Leave a comment The Cookies Statement is part of our Privacy Policy. Yttrium oxide and iron oxide combine to form a crystal garnet used in radar. Its density at room temperature is 4.472g/cm3. The relative atomic mass of Yttrium is 88.90585 u. 7×10-7% (In Universe) We use cookies to ensure that we give you the best experience on our website. Discoverer: Corson, Dale R. and Mackenzie, K. R. The actinide or actinoid series encompasses the 15 metallic chemical elements with atomic numbers from 89 to 103, actinium through lawrencium. We assume no responsibility for consequences which may arise from the use of information from this website. Yttrium occurs in uranium ores and is present in nearly all the 'rare earth' minerals. It is recovered commercially from monazite sand and bastnaesite by reduction of the fluoride with calcium metal. The symbol of resistivity is usually the Greek letter ρ (rho). Yttrium also dissolves oxygen gas in relatively high concentrations. Discoverer: Davy, Sir H. and Thénard, L.-J. Yttrium has an exceptionally high affinity for oxygen, with a free energy of formation for the oxide of 1817 kJ mol-1, probably the greatest of any element. E. Discoverer: De Marignac, Charles Galissard, Discoverer: De Marignac, Jean Charles Galissard, Discoverer: Göhring, Otto and Fajans, Kasimir. Yttrium oxide is also used to produce yttrium-iron-garnets (Y3Fe5O12), which are very effective microwave filters for radar ", ground state electronic configuration of neutral yttrium is. 1) You may use almost everything for non-commercial and educational use. The forces of chemical bonding causes this repetition. Molar volume:  0.000019881 m3/mol The ionization potential of an atom:  6.5 Standard Atomic weight:  88.905  g/mol Yttrium turnings ignite in air. Yttrium nitride is formed when the metal is heated to 1000 oC in nitrogen. 5s2 and the term symbol of yttrium is 2D3/2. 2 Y (s) + 3 I2 (g)  →  2 YI3 (s)       (Yttrium (lll) iodide), Dissolves readily in dilute hydrochloric acid, forming aquated Yttrium (III) ions and hydrogen gas: It is a silvery, ductile, fairly reactive metal that is easily combustible, reacts with oxygen in water to release hydrogen. 90 Yttrium, a radioactive isotope, is used in treatments for various cancers and is used in precision medical needles to sever pain-transmitting nerves in the spinal cord. The boiling point of Yttrium is 3200 Kelvin (2927 ℃). and an insulator, such as glass. Neutron cross section (Brans):  1.28 Young’s modulus:   63.5 GPa Common chemical compounds are also provided for many elements. A crystal lattice is a repeating pattern of mathematical points that extends throughout space. Electron affinity:  29.6 kJ/mol, Half Life:  Stable (Infinity)  2 Y (s) + 3 F2 (g) → 2 YF3 (s)    (Yttrium (lll) fluoride) Yttrium is a rare, silvery, soft, metal.

Discoverer: Coster, Dirk and De Hevesy, George Charles, Discoverer: Elhuyar, Juan José and Elhuyar, Fausto, Discoverer: Noddack, Walter and Berg, Otto Carl and Tacke, Ida. To the right (or below if you are using a mobile device with a smaller screen) you will find the information given above for the element Yttrium ordered in tabular form, which might be easier to read and use if you want to quantify it in some sort. Exposed surfaces form oxide film. It is a silvery, ductile, fairly reactive metal that is easily combustible, reacts with oxygen in water to release hydrogen. 2,141 views Lattice angles:  π/2, π/2, 2π/3 Yttrium - Periodic Table. Main purpose of this project is to help the public learn some interesting and important information about chemical elements, ionizing radiation, thermal engineering, reactor physics and nuclear energy. This small town, near Stockholm, bears the honor of giving names to erbium, terbium, and ytterbium as well as yttrium. It is relatively stable in air due to the formation of an oxide film on its surface. Thermal conductivity:  17.2 W/(m∙K), Electrical conductivity:  1.8×106 S/m Yttrium was discovered by Johan Gadolin in 1794 in the mineral gadolinite. Web. Its shemical symbol is Y and its atomic number is 39. Yttrium oxide is also used to make yttrium iron garnets (Y3 Fe5O12), which are very effective microwave filters. Yttrium has a silvery-metallic lustre. 19×10-5% (In Meteorites) 3) USA, Your email address will not be published. If you continue to use this site we will assume that you are happy with it. It has high melting point, about 1526oC and boiling point is 2903oC. Critical point (Superconducting point):   1.3 K (-271.85 oC, -457.33 oF), A Magnetic type:  Paramagnetic from ionizing radiation) to cross the band gap and to reach the conduction band. The finely divided metal ignites in air when heated. Yttrium Aluminum, Iron, and Gadolinium garnets have interesting magnetic properties. Yttrium is a soft, silver transition metal. Mass Number:  89 YIG is also exceptionally efficient as both a transmitter and transducer of acoustic energy.
