Halogens class 11
WebElectron 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 eg H. Greater the amount of energy released in the above process, higher is the electron gain enthalpy of the element.
