$Na^{+}$

Vedclass · Answer

(D) . $Na^{+} All these ions are isoelectronic,meaning they contain the same number of electrons ($10$ electrons).For isoelectronic species,the ionic radius decreases as the atomic number $(Z)$ increases because the effective nuclear charge increases.Since the atomic numbers are $N(7)$,$O(8)$,$F(9)$,and $Na(11)$,the effective nuclear charge is highest for $Na^{+}$,resulting in the smallest ionic size.
