Further information Description Scandium is apparently a much more abundant element in the sun and certain stars than on earth. Scandium is a silvery-white metal which develops a slightly yellowish or pinkish cast upon exposure to air. It is relatively soft, and resembles yttrium and the rare-earth metals more than it resembles aluminium or titanium.
Scandium reacts rapidly with many acids.
