CHEMISTRY GLOSSARY
electron affinity
elektronski afinitetElectron affinity (EA) is the energy change occurring when an atom or molecule gains an electron to form a negative ion. For an atom or molecule X, it is the energy released for the electron-attachment reaction
X(g) + e- →← X- (g)
This is often measured in electronvolts. Alternatively, the molar enthalpy change, ΔH, can be used.
