Most exothermic electron affinity
Did you know?
WebJan 28, 2016 · Electron affinity is defined as the amount of energy released when one mole of electrons are added to one mole of atoms in the gaseous state to form one mole of negative ions, or anions. X + e− → X− + energy. In simple terms, electron affinity is a measure of the attraction that exists between an atom and an incoming electron. WebThe first ionization energy for sodium is one and one-half times larger than the electron affinity for chlorine. Na: 1st IE = 495.8 kJ/mol. Cl: EA = 328.8 kJ/mol. Thus, it takes more energy to remove an electron from a neutral sodium atom than is given off when the electron is picked up by a neutral chlorine atom.
