WebPeriodic Trends in Element Properties Electron affinity (EA): is a measure of the energy change when an electron is added to a gaseous atom to form an anion S (g) ... • Decreases from left to right because electrons are held closer to the nucleus by the increasingly greater effective nuclear charge (Z eff). WebElectron affinity (the energy associated with forming an anion) is more favorable (exothermic) when electrons are placed into lower energy orbitals, closer to the nucleus. Therefore, electron affinity becomes increasingly negative as we move left to right across the periodic table and decreases as we move down a group.
