Yttrium, is a chemical element that has the symbol Y and atomic number 39. A silvery metallic transition metal, yttrium is common in rare-earth minerals and two of its compounds are used to make the red color phosphors in cathode ray tube displays, such as those used for televisions.
Yttrium is a silver-metallic, lustrous rare earth metal that is relatively stable in air, strongly resembles scandium in appearance, and chemically resembles the lanthanides, and can appear to gain a slight pink lustre on exposure to light. Shavings or turnings of the metal can ignite in air when they exceed 400 °C. When yttrium is finely divided, it is very unstable in air. The metal has a low neutron cross-section for nuclear capture. The common oxidation state of yttrium is +3.
