Electron Gain Enthalpy: Definition, Factors, Variations, Videos ... Variation of Electron Gain Enthalpy within a Group

The electron gain enthalpy becomes less negative as we move down a group. As we move down a group, both the atomic size and the nuclear charge increases. But the effect of the increase in atomic size is much more pronounced than the nuclear charge.

Answer 2

Answer:

The electron gain enthalpy becomes less negative as we move down a group. As we move down a group, both the atomic size and the nuclear charge increases. ... With the increase in atomic size, the attraction of the nucleus for the incoming electron decreases. Hence, the electron gain enthalpy becomes less negative.
