WebJan 8, 2016 · The amount of energy released when an electron is added to a neutral atom to form an anion is called electron affinity. Electron … WebElectron Affinity. As the name suggests, electron affinity is the measure of how much an atom "wants" another electron. When an atom accepts an additional electron, it will either gain or lose energy. Electron affinity is a quantitative measure of that energy change. Electron affinity increases from left to right across the periodic table.

WebApr 8, 2024 · The three factors affecting the electron affinity of a molecule are Nuclear Charge, Atomic Size, and Electronic Configuration.
