Show ExplanationHide Explanation

Explanation

Electron affinity is the energy released when an electron is added to a neutral gaseous atom to form a negative ion, using the usual energy-release convention. Electronegativity instead concerns attraction of bonding electrons. A simple likelihood is not the quantitative definition of electron affinity.
