The order of stability of oxidation state for +3 is$\mathrm{B}{\mathrm{i}}^{3+}>\mathrm{S}{\mathrm{b}}^{3+}>\mathrm{A}{\mathrm{s}}^{3+}$and for +5 is$\mathrm{B}{\mathrm{i}}^{5+}<\mathrm{S}{\mathrm{b}}^{5+}<\mathrm{A}{\mathrm{s}}^{5+}$

In the case of nitrogen, all oxidation states from +1 to +4 tend to disproportionate in acid solution.

There is considerable increase in covalent radius from N to P but from As to Bi only a small increase in covalent radius is observed.

All of these
