Easy MCQ +4 / -1 PYQ · JEE Mains 2020

The ionic radii of O^2–, F^–, Na⁺ and Mg²⁺ are in the order :

A F– > O2– > Na+ > Mg2+
B Mg2+ > Na+ > F– > O2–
C O2– > F– > Mg2+ > Na+
D O2– > F– > Na+ > Mg2+ Correct answer

Solution

Among isoelectronic species, greater the Zeff smaller will be the radius. Order of Zeff : Mg2+ > Na+ > F– > O2– Order of Ionic Radii : O2– > F– > Na+ > Mg2+
