WebElectron affinity The energy released when an electron is added to a neutral gaseous atom is known as electron affinity. The unit for electron affinity is kilo joules per mole. … 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.
