Paramagnetism is due to the presence of unpaired electrons in the material, so most atoms with incompletely filled atomic orbitals are paramagnetic, although exceptions such as copper exist. Due to their spin, unpaired electrons have a magnetic dipole moment and act like tiny magnets.

Why is oxygen paramagnetic in nature?

Based on molecular orbital theory, orbitals are formed by overlapping atomic orbitals of oxygen atoms. ... Due to the presence of two unpaired electrons, we can say that the oxygen molecule is paramagnetic in nature. The reason why oxygen is paramagnetic is because of the presence of two unpaired electrons.

How do you know if nature is paramagnetic?

The magnetic properties of a substance can be determined by examining its electron configuration: If it has unpaired electrons, then the substance is paramagnetic and if all electrons are paired, the substance is then diamagnetic.
