Which of the following is not ferromagnetic:
Correct answer: C. Sb
- A. Fe
- B. Co
- C. Sb
- D. Ni
Explanation
Antimony (Sb) is not ferromagnetic. It is considered a diamagnetic material, which means it is weakly repelled by both poles of a magnet and does not exhibit the strong magnetic properties characteristic of ferromagnetic materials. Therefore, option c 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.
