Question

Assertion (A) : Chlorine has more negative electron gain enthalpy than fluorine.
Reason (R) :Chlorine has smaller atomic radii than fluorine.​

Answer 1

Answer:

A :The negative electron gain enthalpy of fluorine is less than that of chlorine. It is due to small size of fluorine atom. As a result, there are strong interelectronic repulsions in the relatively small 2p orbitals of fluorine and thus, the incoming electron does not experience much attraction.

R: But, F has 9 protons attracting those other electrons wheres O has only 8 protons attracting those outer electrons, This will tend to make F a little smaller in radius than O. F and Cl are in the same group, but F is in period 2 and Cl is in period 3.
