Which of the following transition metals show a 3d5 configuration in their +2 oxidation state?
Correct answer: C. Mn+2
- A. Cu+2
- B. Fe+2
- C. Mn+2
- D. Zn+2
Explanation
Mn²⁺: Manganese in the +2 oxidation state has an electron configuration of [Ar] 3d⁵, which is a half-filled d-subshell, making it stable.

About Transition Elements
Transition elements are identified by their partially filled d subshells in atoms or common ions. The topic covers the electronic structure of d-block elements, including the filling order of 4s and 3d orbitals, variable oxidation states and the distinction between transition elements and elements with completely filled d subshells.
