Consider N3- O2- F- Na+ Mg2+ and Al3+ (a) what is common in them (b) arrange them in a order of increasing ionic radii

Solution

Dear Student,

(a) All the species have the same number of electrons, i.e., 10 electrons. Thus, these are isoelectronic species.
(b) Cations are smaller than anions. Thus, order of ionic radii: Al³⁺<Mg²⁺<Na⁺<F^-<O^2-<N^3-
