Out of these, which metal is paramagnetic?
Correct answer: A. Cr
- A. Cr
- B. Mn
- C. Fe
- D. All of these
Explanation
The presence of unpaired electrons causes a molecule to be paramagnetic. Both manganese and iron have completely filled shells so they will not generate any magnetic field. While chromium does have unpaired electrons and therefore it is a paramagnetic element. Option A is correct.

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.
