Electron affinity by Wikipedia Bot 0
Electron affinity is the amount of energy released or absorbed when an atom or molecule gains an electron to form a negative ion. It is a measure of the tendency of an atom to accept an electron. In more technical terms, the electron affinity of an element is defined as the change in enthalpy (ΔH) that occurs when one mole of electrons is added to one mole of atoms in the gas phase, forming anions.
