More info:
Scandium is the first member of the 3D block elements and the first rare earth elements. Scandium exhibits +3 oxidation state. In Sc3+ state, it has a completely empty 3D sub-shell. For this reason, generally Scandium complexes are colourless. Scandium is also not a transition metal in the true sense since it cannot exist in wide variety of transition states. Scandium has also no known biological role and is a suspected carcinogen.
