In transition elements, the oxidation states vary by unity (due to incomplete filling of d-orbitals), e.g. Mn exhibits +2, + 3, + 4, + 5, + 6 and + 7 all differing by 1.
In non-transition elements, this variation is selective, always differing by 2, e.g. S exhibits +2, +4, +6 oxidation states and N exhibits +3, + 5, etc.
