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.

WebAn element's second ionization energy is the energy required to remove the outermost, or least bound, electron from a 1+ ion of the element. Because positive charge binds electrons more strongly, the second ionization energy of an element is always higher than the first. Created by Jay.

8.8: Electron Affinities and Metallic Character
WebElectron Affinity Ionization energies measure the tendency of a neutral atom to resist the loss of electrons. It takes a considerable amount of energy, for example, to remove an electron from a neutral fluorine atom to form a positively charged ion.
