Consider the isoelectronic species, Na⁺, Mg²⁺,F –and O₂–. The correct order of increasing length of their radii is ...........
A.F–< O₂– < Mg²⁺< Na⁺
B.Mg²⁺< Na⁺ < F– < O₂–✓ Correct
C.O₂–<F–< Na⁺< Mg²⁺
D.O₂–< F– < Mg²⁺< Na⁺
Explanation
1 Isoelectronic species; Ionic Radii eff Z 2 2 order of Zeff value is O F Na Mg Thus, Ionic Radii follows the order 2 2 Mg Na F O
