Paramagnetism

Although it is usually demonstrated with molecular species rather than atoms, paramagnetism of non-metallic species can be an interesting demonstration because students expect only metals to be "magnetic". Paramagnetism is always associated with unpaired electrons, so it can be related to the order of filling of p and d sublevels. The paramagnetism of transition metal complexes[1] is easy to demonstrate[2][3][4].

Paramagnetism of liquid oxygen is a well known demonstration [5][6]
