How is  the  variability in oxidation states of  transition metals different  from  that of  the non‐ transition metals? Illustrate with examples. 

Answer»

The transition elements use its (n‐1)d, ns and np orbital and the successive oxidation states differ by unity. For example, Mn shows all the oxidation states from +2 to +7. On other hand non transition elements use its ns, np and nd orbitals and the successive oxidation states differ by two units e.g. Sn2+, Sn4+ etc.
