$Na^{+}$

Vedclass · Answer

(D) The given ions $N^{3-}$,$O^{2-}$,$F^{-}$,and $Na^{+}$ are isoelectronic species,meaning they all have the same number of electrons ($10$ electrons).For isoelectronic species,the ionic radius decreases as the nuclear charge (atomic number,$Z$) increases.The atomic numbers are: $N (Z=7)$,$O (Z=8)$,$F (Z=9)$,and $Na (Z=11)$.Since $Na^{+}$ has the highest nuclear charge $(Z=11)$,it exerts the strongest attraction on the electrons,resulting in the smallest ionic radius.
