WebWhat is Electron Affinity? The energy released when an electron is added to a neutral atom to produce a negatively charged ion is called electron affinity. Only a few chemical elements, mostly halogens, have measured electron affinities. WebAug 31, 2024 · Electron affinity (E.A.) is the energy change that occurs when an electron is added to a gaseous atom. Electron affinity can further be defined as the enthalpy change that results from the addition of an electron to a gaseous atom. It can be either positive or negative value. The greater the negative value, the more stable the anion is.
