Why Does Ionization Energy Increases Across A Period: Detailed ...

WebNov 14, 2024 · The electron affinity ( EA) is the energy released to add an electron to an elements in the gaseous state. In general successive electron affinity increase in magnitude EA1 < EA2 < EA3 and so on. First electron affinity increases across the period First electron affinity decreases down the group Exceptions are nitrogen, fluorine, … WebAs the radius decreases acrosss a period, the ionisation energy keeps on increasing as we move across a period. It is maximum for nobel gases. Electorn affinity – This property is … WebElectron affinity is the energy produced when a gaseous neutral atom absorbs an electron and becomes a negatively charged ion. When the initial electron is added to an atom, a monovalent anion is released, releasing energy. Adding another electron to this anion repels it, absorbing energy. Further electron affinities are positive. bms in the uk
