Which is a pair of paramagnetic species?
Correct answer: A. KO2 , NO 2
- A. KO2 , NO 2
- B. K2O2 , KO2
- C. K2O, NO2
- D. NO2 , N2O2
Explanation
In KO2, O-2 → (superoxide) has one unpaired electron and NO2also has one unpaired electron. Thus, KO2 and NO2 are paramagnetic.

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
