Unpaired electron in a molecule gives ______________ character ?
Correct answer: B. Paramagnetic
- A. Ferromagnetic
- B. Paramagnetic
- C. Diamagnetism
- D. Both A & B
Explanation
An unpaired electron has a magnetic moment, so a molecule containing one or more unpaired electrons is attracted by an external magnetic field and is paramagnetic. Ferromagnetism is a special collective property of certain solids, not the usual classification for an individual molecule. The likely mistake is choosing a because both terms involve magnetism.

About Electronic Configuration
Electronic configuration describes how electrons occupy shells, subshells and orbitals around an atom. Questions use the Aufbau principle, Pauli exclusion principle and Hund's rule to write configurations, identify valence electrons, form ions and explain periodic trends, including common exceptions such as chromium and copper.
