Question

Explain the electron gain enthalpy?

Answer 1

Enthalpy is basically the amount of energy exchanged by a system as heat (and/or internal energy) during a process. Electron Gain Enthalpy - It is the enthalpy change which takes place when an isolated gas atom accepts electron to form a monovalent gaseous anion.

Answer 2

Explanation:

Electron gain enthalpy of an element is the energy released when a neutral isolated gaseous atom accepts an extra electron to form the gaseous negative Ion i.e. anion. We can denote it by Δ egH. Greater the amount of energy released in the above process, higher is the electron gain enthalpy of the element.
