Answer:
In chemistry and atomic physics, the electron affinity of an atom or molecule is defined as the amount of energy released or spent when an electron is added to a neutral atom or molecule in the gaseous state to form a negative ion.
It is the energy released (per mole of X) when this change happens. Firstelectron affinities have negative values. For example, the first electron affinity of chlorine is -349 kJ mol-1.
