The isoelectronic ions ionic radii of anions is more than that of cations further the size of anion increases with increases in negative charge $4^{\text {th }}$ size of the cation decrease with increases in positive charge. The increasing of the size of ions are:$\mathrm{Ca}^{2+}<\mathrm{K}^{+}<\mathrm{Ar}<\mathrm{Cl}^{-}<\mathrm{S}^{2-}$

The set of elements that differ in mutual relationship from those of the other sets is
1 Li-Mg
2 $\mathrm{B}-\mathrm{Si}$
3 Be-Al
4 $\mathrm{Li}-\mathrm{Na}$
Explanation:
$\mathrm{Li}-\mathrm{Mg}, \mathrm{Be}-\mathrm{Al}$ and $\mathrm{B}-\mathrm{Si}$ show as diagonal relationship but $\mathrm{Li}$ and $\mathrm{Na}$ do not show diagonal relationship as both belongs to some group and not placed diagonally.

The set of elements that differ in mutual relationship from those of the other sets is:
1 $\mathrm{Be}-\mathrm{Al}$
2 $\mathrm{B}-\mathrm{Si}$
3 $\mathrm{Li}-\mathrm{Na}$
4 $\mathrm{Li}-\mathrm{Mg}$
Explanation:
Be-Al, B-Si, Li-Mg have the diagonal relationship whereas $\mathrm{Li}-\mathrm{Na}$ are of the same group element and have the other properties than diagonal relationship sets. So, $\mathrm{Li}$ and $\mathrm{Na}$ does not have diagonal relationship.
