WebThe electron affinity of an element is the energy change which accompanies the addition of an electron to an atom in the gas phase to produce a negatively charged anion: X (g) + e- ® X - (g) Electron affinities are usually negative values, since energy is usually released (an exothermic energy change) when an electron is added to a neutral ... WebA trend of decreasing electron affinity down the groups in the periodic table would be expected since the additional electron is entering an orbital farther away from the nucleus. Since this electron is farther away, it should be less attracted to the nucleus and release less energy when added. However, this trend applies only to Group-1 atoms ...
