Does yttrium oxidize?
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.
How many isotopes does yttrium have?
Isotopes: Yttrium has 25 isotopes whose half-lives are known, with mass numbers 79 to 103. Naturally occurring yttrium consists of its one stable isotope, 89Y.
How many valence electrons does yttrium give up?
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. 3), also known as yttria, a six-coordinate white solid.
What is the thermal conductivity of yttrium oxide?
Yttrium oxide, also known as yttria, is Y2O3. It is an air-stable, white solid substance. Yttrium oxide is used as a common starting material for both materials science as well as inorganic compounds . The thermal conductivity of yttrium oxide is 27 W/(m·K).
How is pure yttrium obtained from mixed oxides?
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. With the addition of oxalic acid, the yttrium oxalate precipitates. The oxalate is converted into the oxide by heating under oxygen.
How is yttrium classified as a rare earth element?
Yttrium is a chemical element with the symbol Y and atomic number 39. It is a silvery-metallic transition metal chemically similar to the lanthanides and has often been classified as a “rare-earth element”. Yttrium is almost always found in combination with lanthanide elements in rare-earth minerals, and is never found in nature as a free element.
