CHXII08:THE D- & F-BLOCK ELEMENTS

321528 The variability of oxidation state

1 is a characteristic of transition elements
2 arises out of incomplete filling of d-orbitals in such a way that their oxidation states differ from each other by unity
3 it differs from the variability of oxidation states of non-transition elements where the oxidation states normally differ by a unit of two.
4 All the above are true.
