The tendency to exhibit —3 oxidation state decreases down the group due to increase in size and metallic group. In the last member of the group, bismuth hardly forms any compound in —3 oxidation state. Because of the extra stable half filled p orbitals electronic configuration and smaller size, the ionization enthalpy of the group 15 elements is much greater than that of group 14 elements in the corresponding periods.

However, amongst the heavier elements, the different is not that much pronounced. Chapter Chosen The p-Block Elements. Book Chosen Chemistry I. Subject Chosen Chemistry.
