Nov 19, 2017· Yttrium has the electronic configuration Kr 5s2 4d1. This means that it tends to react by losing 3 electrons and forming a 3+ ion. Oxygen forms 2- ions by gaining 2 electrons. Therefore, 2 yttrium atoms transfer 6 electrons to 3 oxygen atoms, making two yttrium 3+ ions and three oxide (2-) ions and thus the formula of yttrium oxide is #Y_2O_3#.
Sep 15, 2019· yttrium - Yttrium is an element element with an atomic number of 39 and atomic weight of 88.90585. It is a dark gray metal that is used to make alloys for nuclear technology because the element has a high neutron transparency.
Yttrium has a silver-metallic luster and is relatively stable in air. Turnings of the metal, however, ignite in air if their temperature exceeds 400°C. Finely divided yttrium is very unstable in air. Uses. Yttrium oxide is one of the most important compounds of yttrium and accounts for the largest use.
Yttrium | Y | CID 23993 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards ...
Ytterbium is a chemical element with the symbol Yb and atomic number 70. It is the fourteenth and penultimate element in the lanthanide series, which is the basis of the relative stability of its +2 oxidation state. However, like the other lanthanides, its most common oxidation state is +3, as in its oxide, halides, and other compounds.
Yttrium atoms have 39 electrons and the shell structure is 2.8.18.9.2. The ground state electronic configuration of neutral yttrium is [Kr].4d 1.5s 2 and the term symbol of yttrium is 2 D 3/2.. Yttrium: description Your user agent does not support the HTML5 Audio element.
A chemical symbol is a notation of one or two letters representing a chemical element. The exceptions to the one- to two-letter symbol are the temporary element symbols assigned to designate new or to-be-synthesized elements. Temporary element symbols are three letters that are based on the element.
Yttrium oxide in glass makes it heat- and shock-resistant, and is used for camera lenses. Yttrium oxide is suitable to making superconductors, which are metal oxides which conduct electricity without any loss of energy. Yttrium in the environment. Yttrium never occurs in nature as a free element.
Yttrium chemical properties define its chemical formula, isotopes, oxides, electronegativity
Element Yttrium - Y. 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. Common chemical compounds are also provided for many elements.
Oct 24, 2019· Before a name and symbol are approved, an element may be referred to by its atomic number (e.g., element 120) or by its systematic element name. The systematic element name is a temporary name that is based on the atomic number as a root and the -ium ending as a suffix. For example, element 120 has the temporary name unbinilium.
Yttrium oxide (Y 2 O 3) Yttrium fluoride (YF 3) Yttrium chloride (YCl) Yttrium vanadate (YVO 4) Interesting facts: It does not occur as a free element in nature. It is highly toxic. Common Uses: Microwave filters; Magnets; Gemstones; Increase strength of aluminum and magnesium alloys; Infrared lasers; Spark plugs; Deoxidizers; Propane lanterns ...
Yttrium aluminum garnets, with a hardness of 8.5, are used to simulate diamond gemstones. 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 is used as a deoxidizer for vanadium and other nonferrous metals.
Reaction of yttrium with air. Yttrium metal tarnishes slowly in air and burns readily to form yttrium (III) oxide, Y 2 O 3. 4Y + 3O 2 → 2Y 2 O 3. Reaction of yttrium with water. When finely divided, or heated, yttrium metal dissolves in water to form solutions containing the aquated Y(III) ion together with hydrogen gas, H 2.
Yttrium Chloride Chemical Formula. Yttrium Chloride also known as Yttrium III Chloride is a inorganic chemical compound with chemical formula YCl 3. It is a white solid and has molar mass of 195.26 g/mol. It is prepared by the "ammonium chloride route". It is present in two forms as hydrated (YCl 3 (H 2 O) 6)) and anhydrous form (YCl 3).
Because yttrium is an element, it can't be broken down any further by chemical means, but it can be combined with other elements. Yttrium is represented by the symbol ''Y'' and the atomic number 39.
Yttrium (Y), chemical element, a rare-earth metal of Group 3 of the periodic table. Yttrium is a silvery white, moderately soft, ductile metal. It is quite stable in air; rapid oxidation begins above approximately 450 °C (840 °F), resulting in Y2O3. The metal readily reacts with diluted

This is not a question. Y is the symbol for the element yttrium. Until about 20 years ago, most scientists had not heard of it, other than vaguely noting where it was in the periodic table, under scandium and above lanthanum. Some people might just have known that it was one of 4 chemical elements named after the small Swedish town of Ytterby ...
