Solution

Dear Student,

Electronic Configuration of Scandium : [Ar] 3d¹4s²

Electronic Configuration of Sc⁺³ : [Ar] 3d⁰4s⁰

In Sc⁺³, Number of electrons in 3d and 4s orbital is zero and its electronic configuration is noble gas ( Argon) configuration which is very stable. Moreover Scandium do not have sufficient electrons in d orbital to show variable oxidation state.

Regards,
