WebNov 26, 2024 · Electron Affinity. In chemistry and atomic physics, the electron affinity of an atom or molecule is defined as: the change in energy (in kJ/mole) of a neutral atom or molecule (in the gaseous phase) when an electron is added to the atom to form a negative ion. X + e – → X – + energy Affinity = – ∆H Electron affinity is defined as The electron affinity is the potential energy change of the atom when an electron is added to a neutral gaseous atomto form a negative ion. So the more negative the electron affinity the more favourable the electron addition process is. Not all elements form stable negative … See more The amount of energy released when an electron is added to a neutral atom to form an anion is called electron affinity.
