Vedclass · Answer

(D) Cations lose electrons and are smaller in size than the parent atom,whereas anions gain electrons and are larger in size than the parent atom. For the hydrogen species,the order is $H^{-} > H > H^{+}$. For isoelectronic species,the ionic radius decreases as the atomic number (nuclear charge) increases. Comparing $O^{2-}$,$F^{-}$,and $Na^{+}$,all have $10$ electrons. Their atomic numbers are $8$,$9$,and $11$ respectively. Therefore,the correct order of ionic radii is $O^{2-} > F^{-} > Na^{+}$. Since none of the provided options $A$,$B$,or $C$ correctly represent this order,the correct answer is $D$.
