WebTHe electron affinity is the nergy required to detach an electron from the singly charged negative ion (energy for the process X -> X + e). The equivalent more common definition is the energy released (E initial + E final) when an additional electron is attached to a neutral atom or molecule. WebJan 30, 2024 · The electron affinity is a measure of the attraction between the incoming electron and the nucleus - the stronger the attraction, the more energy is released. The factors which affect this attraction are exactly the same as those relating to ionization …
