Vedclass · Answer

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