The amount of energy released when 1 mole of electrons combine, one with each of 1 mole of charge-neutral, isolated gaseous atoms of an element, joining the outermost energy level of the atoms to create 1 mole of singly negatively charged gaseous ions, is the electron affinity of that element.
Electron Affinity (Electron Affinities): The energy released when one mole of electrons is added to one mole of gaseous atoms of an element in the gaseous state, converting them into negative ions, is called the electron affinity of that element.
