WebElectron affinity is measured in electron volts per atom or kilojoules per mole. It is denoted by a minus sign [-] for example, Cl (g) + e- → Cl- (g) + 349 KJ/mol As a result, chlorine's electron affinity is – 349 KJ/mol. Dielectric Constant Born-Haber Cycle Non-Metals Versus Metals [Click Here for Sample Questions] WebThe electron affinity (E ea) of a neutral atom or molecule is defined as the amount of energy released when an electron is added to it to form a negative ion. This can be shown for the chloride ion formation below: Cl …
