What is the trend of number of unpaired electrons for transition elements across a period?
Correct answer: B. Increases till Mn and then decreases till Zn
- A. Always decreases across a period
- B. Increases till Mn and then decreases till Zn
- C. Always increases across a period
- D. Decreases till Mn and increases till Zn
Explanation
The trend of unpaired electrons in transition metals across a period is sporadic and not constant, it increases till Mn and then decreases till Zn.

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.
