- Sc; at. wt 44.955912; at. no. 21; valence 3. Group IIIb (3). Rare earth metal. Naturally occurring isotope (mass number): 45; known artificial radioactive isotopes: 40-44, 46-51. Abundance in earth's crust: 5-25 ppm. Widely dispersed in nature. Occurs in the minerals thortveitite [(Sc,Y)2Si2O7] and in other rare earth minerals such as davidite, ytterbite, orthite and cerrite; frequently associated with tin or zirconium. Predicted and called "ekaboron" by Mendeleev. Discovered by Nilson: Ber. 12, 551, 554 (1879); 13, 1430, 1439 (1880). Sepn from wolframite: Lukens, J. Am. Chem.
