Scandium Data Sheet

Scandium is a silvery white, moderately soft metal.It is fairly stable in air but will slowly change its colour from silvery white to a yellowish appearance because of formation of Sc 2 O 3 oxide on the surface. The metal slowly dissolves in diluted acids—except hydrofluoric acid (HF), in which a protective trifluoride layer prevents further reaction. . Scandium is paramagnetic from 0 K ...
