Scandium | chemical element |

Scandium: Scandium (Sc), chemical element, a rareearth metal of Group 3 of the periodic table. 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 Sc2O3 oxide on the surface.
