Question

Which of the following ions acts as a typical transition metal ion?

Options

• Cu⁺

• Sc⁺

• Ti⁴⁺

• Cr⁶⁺

Answer 1

Sc⁺ 

Explanation:

Typical transition ⇒ d-orbital in the process of filling neither completely filled nor entirely vacant

\[\ce{CU+ : (Ar) 3d^10 Sc+ : [Ar] 3d^1 4s^1}\]

\[\ce{Ti^{4+} : [Ar] Cr^{6+} : [Ar]}\]
