Question

Two elements which have maximum differnce in electron gain enthailpy

Answer 1

Answer:

The elements are chlorine and fluorine.

Explanation:

Chlorine has the maximum electron gain enthalpy. Halogens have the highest electron gain enthalpy (electron affinity). Normally electron affinity decreases as we move down the group. However, fluorine has a lower value than chlorine which is due to its small size.
