Ionization Energy and Electron Affinity - Purdue University
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. These values were obtained from measurements of heats of formation and … portmore hotels
