Yttrium (Y), chemical element, a rareearth 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
Basic information, atomic structure, and isotopes.
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 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).
Yttrium has an exceptionally high affinity for oxygen, with a free energy of formation for the oxide of 1817 kJ mol1, probably the greatest of any element. Yttrium also dissolves oxygen gas in relatively high concentrations. (7), (8) Uses of Yttrium. Yttrium is often used in alloys, increasing the strength of aluminum and magnesium alloys.
Yttrium (Y) has an atomic mass of 39. Find out about its chemical and physical properties, states, energy, electrons, oxidation and more.
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.
A chemical symbol is a notation of one or two letters representing a chemical element. The exceptions to the one to twoletter symbol are the temporary element symbols assigned to designate new or tobesynthesized elements. Temporary element symbols are three letters that are based on the element.
