Question

Scandium does not exhibit variable oxidation states and yet it is regarded as a transition element. Give reason.

Answer 1

Dear Student,
Sc (21) has outer most configuration as $3d^{1}4s^2$. It can loose electrons to form ion having +3 oxidation state. It also contain partially filled d orbital in its ground state which is sufficient enough for an element to be considered as a TRANSITION ELEMENT.
