Electron gain Enthalpy Electron gain enthalpy of an element may be defined as the energy released when a neutral isolated gaseous atom accepts an extra electron to form the gaseous negative Ion i.e. anion.It is denoted by Δ eg H. Greater the amount of energy released in the above process, higher is the electron gain enthalpy of the element. The electron gain enthalpy of … [Read more...] about Electron Gain Enthalpy
