Title: Yttrium
CAS Registry Number: 7440-65-5
Literature References: Y; at. wt 88.90585; at. no. 39; valence 3. Group IIIb (3). A rare earth metal. Naturally occurring isotope (mass number): 89; known artificial radioactive isotopes: 80-88; 90-100. Estimated abundance in earth's crust: 28.1-31 ppm. Natural sources: xenotime, fergusonite, samarskite, yttrialite, gadolinite, and other rare earth minerals. Discovered in 1794 by Gadolin; separated as yttria in 1843 by Mosander; named by Ekeberg.
