Difference between Electronegativity and Electron Affinity

The Major Difference Between Electronegativity And Electron Affinity is that Electronegativity is a chemical property that decides the tendency of an atom to attract electron in a covalent bond, for example, Cl-F while Electron Affinity is the amount of energy that an atom exerts when an electron is added to neutral atom to make it into negative ion i.e. Cl+ e- → Cl-.

electron affinity describes the release of energy to the surrounding while electronegativity is the tendency of an atom to attract the shared pair of electron.

Electronegativity Electron affinity
It is the tendency of an element to attract shared pair of electron towards itself. It is the minimum amount of energy released when a gaseous atom absorbs an electron from the surroundings.
It has no unit. It has a unit.
It helps in predicting the nature of bond form between atoms. It helps in predicting either a chemical substance oxidizing or reducing agent.
