WebScandium is the first element of the3dtransition series with atomic number21 Its oxidation states are2and3 For removing one electron very high amount of energy is required … WebOct 21, 2013 · Scandium has the electronic structure [Ar] 3d1 4s2. When it forms ions it always looses the 3 outer electrons and ends up with an [Ar] structure. The scandium 3 ions has no d electrons i.e. it forms no ion with a partly filled 3d sub–shell as most of the transition metals do. Due to which it does not exhibit variable oxidation states.

Scandium is a soft metal with a silvery appearance. It develops a slightly yellowish or pinkish cast when oxidized by air. It is susceptible to weathering and dissolves slowly in most dilute acids. It does not react with a 1:1 mixture of nitric acid (HNO3) and 48.0% hydrofluoric acid (HF), possibly due to the formation of an impermeable passive layer. Scandium turnings ignite in the air with a brilliant yellow flame to form scandium oxide.
