WebYttrium 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". [5] WebTerbium compounds are compounds formed by the lanthanide metal terbium (Tb). Terbium generally exhibits the +3 oxidation state in these compounds, such as in TbCl 3, Tb (NO 3) 3 and Tb (CH 3 COO) 3. Compounds with terbium in the +4 oxidation state are also known, such as TbO 2 and BaTbF 6. [1]
