Vedclass · Answer

(A) The given ions $N^{3-}$,$O^{2-}$,$F^{-}$,$Na^{+}$,and $Mg^{2+}$ are isoelectronic species,as each contains $10$ electrons.For isoelectronic species,the ionic radius increases as the nuclear charge (atomic number) decreases.The atomic numbers are: $N(7)$,$O(8)$,$F(9)$,$Na(11)$,$Mg(12)$.Since the nuclear charge follows the order $N O^{2-} > F^{-} > Na^{+} > Mg^{2+}$.Therefore,the correct order of increasing ionic radii is $Mg^{2+} < Na^{+} < F^{-} < O^{2-} < N^{3-}$.

$Column\, A$ (ion)	$Column\, B$ (radius)
$(i)$ $Li^{+}$	$(p)$ $216\, pm$
$(ii)$ $Na^{+}$	$(q)$ $195\, pm$
$(iii)$ $Br^{-}$	$(r)$ $60\, pm$
$(iv)$ $I^{-}$	$(s)$ $95\, pm$
