Give reasons: The stability of +3 oxidation state of 13 group elements

1.	Give reasons: The stability of +3 oxidation state of 13 group elements decreases down the group.
Answer» Solution :The stability of +3 oxidation state of group 13 elements decreases down the group DUE to the inert pair effect on ns2 electrons. This is because of the POOR SHIELDING effect of electron in d and f orbitals.
