The maximum oxidation shown by manages is_________?
Correct answer: D. +7
- A. +2
- B. +4
- C. +5
- D. +7
Explanation
The maximum oxidation state of manganese is +7, as in permanganate, MnO4−. Students often choose +2 because Mn2+ is its especially stable and common oxidation state, but that is not its maximum oxidation state.

About Electronic Structure of d-Block Elements
The electronic structure of d-block elements covers the filling of the (n-1)d and ns orbitals, general electronic configurations, and the exceptions shown by chromium and copper. It explains how partially filled d orbitals produce variable oxidation states, coloured ions, magnetic behaviour and complex formation, while distinguishing transition elements from elements with completely filled d subshells.
