WebThe electronic affinity is amount of energy, that is released during the attachment of the electron to the neutral atom. As a result of such attachment, a negative ion (anion) is formed. Electron affinity is related to electronegativity of elements.Simply speaking, the greater the affinity of electrons, the more eagerly the atoms of a given element join … 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.
