Question

Why is ${\mathrm{KO}}_2$ paramagnetic?

Answer 1

Potassium superoxide:

1. The inorganic compound Potassium superoxide has the formula ${\mathrm{KO}}_2$.
2. It is a paramagnetic yellow solid that breaks down in damp air.

Magnetic nature:

1. The superoxide ${\mathrm{KO}}_2$ has an odd number of electrons (unpaired electrons).
2. As a result, ${\mathrm{KO}}_2$ is a paramagnetic substance.

Hence, ${\mathrm{KO}}_2$ is paramagnetic.
