1.	The lower electron affinity of fluorine than that of chlorine is due toA. Smaller sizeB. smaller unclear chargeC. difference in their electronic configurationsD. its highest reactivity
Answer» Because of the small size of F, electron-electron repulsions present in its relatively compact 2p-subshell, do not easily allow theaddition of an extra electron. On the other hand, Cl because of its comparatively bigger size than F, allows the addition of an extra electron more easily. Thus, the EA of Cl is higher than that of F.
