Those elements which have paired electrons are diamagnetic and weakly repelled by the external magnetic field. Einstein demonstrated that electricity and magnetism are inextricably linked in his theory of special relativity. e the total free-electrons density and This causes the magnetic fields of the electrons to cancel out; thus there is no net magnetic moment, and the atom cannot be attracted into a magnetic field. Although there are usually energetic reasons why a molecular structure results such that it does not exhibit partly filled orbitals (i.e. First ionization energy= 500kJ/mol Hydrogen is therefore diamagnetic and the same holds true for many other elements. Even if is close to zero this does not mean that there are no interactions, just that the aligning ferro- and the anti-aligning antiferromagnetic ones cancel. The quenching tendency is weakest for f-electrons because f (especially 4f) orbitals are radially contracted and they overlap only weakly with orbitals on adjacent atoms. Because unpaired electrons can spin in either direction, they display magnetic moments in any direction. Let us explain it. This is why s- and p-type metals are typically either Pauli-paramagnetic or as in the case of gold even diamagnetic. Allotropic forms are the different forms of a chemical element. Inconsistent with the general trend relating changes in ionization energy across a period from left to right and due to the fact that oxygen has one doubly occupied 2p orbital and nitrogen does not.
