Question

Which element has higher value of negative electron gain enthalpy for cl?

Answer 1

Chlorine (Cl) has more negativeelectron gain enthalpy than fluorine (F). F has less negative electron gain enthalpy because in it the addedelectron goes to the smaller energy level (n=2) and hence suffers significant repulsion from theelectrons already present in this shell.

Answer 2

Answer:

Chlorine gives highest electron gain enthalpy rather than flourine
