Question

which halogen has the highest value of negative electron gain enthalpy​

Answer 1

Answer:

Explanation:

Halogens have highest negative value of electron gain enthalpy. Here Cl and F both are halogens but electron gain enthalpy of Cl is more negative than F because of very small size of F which causes interelectronic repulsion among its electrons. P has the lest negative one due to larger size.
