WebNoble gases have a stable electronic configuration as their octet is complete. They cannot accept more electrons. Electron affinity is the energy released when an isolated atom gains an electron. Since noble gases cannot accept electrons, their electron affinity is zero. Therefore, noble gases have zero electron affinity. Webelectron affinity, in chemistry, the amount of energy liberated when an electron is added to a neutral atom to form a negatively charged ion. The electron affinities of atoms are difficult to measure, hence values are available for only a few chemical elements, chiefly the halogens.

WebElectron affinity refers to the ability of elements to release energy, thus showing the ease and spontaneity, of adding an extra electron to the sole atom. Another difference is that electronegativity is a value from 0 to 4.0, while electron affinity is a defined thermodynamic constant for each element in kJ per mole.
