What is Electron Affinity? - Definition, Trends

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. WebThe amount of energy released when an atom in the gaseous state accepts an electron to form an anion. Factors which affect electron affinity are: Atomic size and Nuclear charge. As atomic radii increases, electron affinity increases. As nuclear charge increases, electron affinity increases. It decreases down a group and increases across a period.
