The correct order of increasing ionic radii is
Solution
For isoelectronic species<br/><br/>
Ionic radii $\propto \frac{(-) \text { ve charge }}{(+) \text { ve charge }}$<br/><br/>
Hence, correct order of ionic radii is<br/><br/>
Mg<sup>2+</sup> < Na<sup>+</sup> < F<sup>–</sup> < O<sup>2–</sup> < N<sup>3–</sup>
