The molecular of oxygen has two unpaired electrons. It is therefore:
Correct answer: B. paramagnetic
- A. diamagnetic
- B. paramagnetic
- C. ferromagnetic
- D. electromagnetic
Explanation
Those substances which have at least only one unpaired electron are called diamagnetic substances. They are weakly repelled in direction of magnetic field.

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.
