Electron affinity factors

WebThe factors that influence electron affinity are electronic configuration, atomic size,nuclear charge and shielding effect. The periodic trends of electron affinity are: going across … The electron affinity (Eea) of an atom or molecule is defined as the amount of energy released when an electron attaches to a neutral atom or molecule in the gaseous state to form an anion. X(g) + e → X (g) + energy This is not the same as the enthalpy change of electron capture ionization, which is defined as negative when energy is released. In other words, the enthalpy change and the electron affinity …

WebSep 27, 2024 · Factor Influencing Electron Affinity. Like ionization energy, electron affinity is influenced by atomic radius, the nuclear charge and the shielding effects of inner electrons. As the force of attraction between the valence electrons and the nucleus decreases with the increase in the atomic radius, the electron affinities usually … WebMar 31, 2024 · The electron gain enthalpy of an atom can be considered as a measure to gain an electron and form an anion. The higher the energy released during this process, the easier will be the formation of an anion. Elements of groups 16 and 17 have more negative values of electron gain enthalpies hence they have a tendency to form ionic compounds. cmd create new user https://phase2one.com
