Consider the following species : N^3-, O^2-, F^-, Na⁺, Mg²⁺ and Al³⁺(a) What is common in them?
(b) Arrange them in the order of increasing ionic radii.

(a) Each one of these ions contains 10 electrons and hence all are isoelectronic ions.

(b The ionic radii of isoelectronic species increase with a decrease in the magnitudes of nuclear charge. The arrangement of the given species in order of their increasing nuclear charge is as follows:

N^3-< O^-2<F^-<Na⁺<Mg²⁺<Al³⁺
