It is found in thortveitite and, in small amounts, in other minerals. Scandium is a soft metal used as a radioactive tracer and in nickel alkaline storage batteries. Chemically it resembles the rare-earth metals of the lanthanide series. Properties: at.no. 21; r.a.m. 44.956; r.d 2.99; m.p. 1539°C (2802°F); b.p. 2832°C (5130°F); most common isotope Sc45 (100%).
