Para+and+Diamagnetism

__**Paramagnetic:**__ A paramagnetic molecule is a molecule that is attracted to a magnetic field because it contains unpaired electrons. The more unpaired electrons, the stronger the force of attraction.

ex: Fe [18Ar] 4s2 3d6 (↑↓) (↑↓) **(↑)(↑)(↑)(↑)**

__**Diamagnetic:**__ A diamagnetic molecule is a molecule that is weakly repelled from a magnetic field because it has no unpaired electrons. Paramagnetism is a much stronger effect than diamagnetism.

ex: Mg [10Ne] 3s2
