The correct order of the ionic radii of O2–, N3–, F–, Mg2+ Na+ and Al3+ is : (1) N3– < F– < O2– < Mg2+ < Na+ < Al3+ (2) Al3+ < Mg2+ < Na+ < F– < O2– < N3– (3) Al3+ < Na+ < Mg2+ < O2– < F– < N3– (4) N3– < O2– < F– < Na+ < Mg2+ < Al3+

(2) Al3+ < Mg2+ < Na+ < F– < O2– < N3– Explanation: Al3+ < Mg2+ < Na+ < F– < O2– < N3– All are isoelectronic species so more is the zeff less will be the ionic size.

The correct order of the ionic radii of O^2–, N^3–, F^–, Mg²⁺ Na⁺ and Al³⁺ is :

(1) N^3– < F^– < O^2– < Mg²⁺ < Na⁺ < Al³⁺

(2) Al³⁺ < Mg²⁺ < Na⁺ < F^– < O^2– < N^3–

(3) Al³⁺ < Na⁺ < Mg²⁺ < O^2– < F^– < N^3–

(4) N^3– < O^2– < F^– < Na⁺ < Mg²⁺ < Al³⁺

(2) Al³⁺ < Mg²⁺ < Na⁺ < F^– < O^2– < N^3–

Explanation:

Al³⁺ < Mg²⁺ < Na⁺ < F^– < O^2– < N^3–

All are isoelectronic species so more is the z_eff less will be the ionic size.
