WebChemists define electron affinity as the change in energy, measured in units of kJ/mole, experienced when an electron is added to a gaseous atom. This process creates a negative ion. This process differs from electronegativity, which we define as the ability of an atom to attract an electron toward itself. We tend to liken electron affinity to ...
