WebJun 1, 2015 · The energy of an electron in vacuum (isolation from the nucleus) is zero (because it cannot feel the nucleus' attractive pull). But when it occupies a definite energy level in the atom, the energy of the system reduces. The extra energy is then released, which is why you find that the electron gain is generally exothermic. WebApr 6, 2024 · The electron gain enthalpy is also affected by shielding electrons between the nucleus and electron which we are observing. If the number of shielding electrons increases the effective nuclear charge decreases and negative electron gain enthalpy also decreases. ... When a neutral gaseous electron gains an electron, the energy change is …
