WebJan 30, 2024 · The first electron affinity is the energy released when 1 mole of gaseous atoms each acquire an electron to form 1 mole of gaseous -1 ions. It is the energy released (per mole of X) when this change happens. First electron affinities have negative values. For example, the first electron affinity of chlorine is -349 kJ mol -1. WebAug 6, 2024 · First, we have to overcome the nuclear force. To overcome nuclear forces, we provide the gaseous atom of Magnesium with energy. When an atom absorbs energy it becomes an unstable atom and excites an electron to attain stability back. So that minimum about of energy that can cause the removal of electrons is known as ionization energy.
