Vedclass · Answer

(B) The correct order for ionisation energy is $Ca^{2+} > K^{+} > Cl^{-} > S^{2-}$. For isoelectronic species,$I.E. \propto Z_{eff}$.$(b)$ The correct order for $2^{nd}$ ionisation energy is $C $(c)$ The correct order for electronegativity is $B > Tl > In > Ga > Al$. In general,$EN$ increases in the boron family from top to bottom due to an increase in $Z_{eff}$ on the valence shell,while boron has the highest $E.N.$ due to its very small size.$(d)$ The correct order for ionic radius is $Na^{+} > Li^{+} > Mg^{2+} > Al^{3+} > Be^{2+}$. Ionic radius depends on $Z_{eff}$ and the number of shells.
