Scandium Scandium crystals
Scandium is the first transition metal and the first rare earth element, the latter also includes yttrium and the lanthanoids. The ignoble light metal has only a few applications, because its chemistry isn't so complex and it also is rather expensive. It is used in high-quality, light alloys, e.g. for frames of racing bicycles.

Scandium with thin oxide layer Oxidized scandium
Left: Scandium, slightly oxidized in air and therefore a bit yellowish.
Right: Scandium powder, stronger oxidized (about 1% Sc2O3). 3 grams, vial diameter 2 cm.
