1 Σεπ 2024 · Electron affinity is the amount of energy change (ΔE) that occurs when an electron is added in the outermost shell of an isolated gaseous atom. In other words, when the electron is added to a neutral atom, the energy is either released or absorbed.
Explore how electron affinity changes with atomic number in the periodic table of elements via interactive plots.
The electron affinities E ea of some molecules are given in the table below, from the lightest to the heaviest. Many more have been listed by Rienstra-Kiracofe et al. (2002). The electron affinities of the radicals OH and SH are the most precisely known of all molecular electron affinities.
What is electron affinity. Learn its equation, examples, values, and change across a period & down a group in the periodic table. Also, learn its exceptions.
Interactive periodic table showing names, electrons, and oxidation states. Visualize trends, 3D orbitals, isotopes, and mix compounds. Fully descriptive writeups.
20 Σεπ 2022 · Electron affinity is a measure of the energy released when an extra electron is added to an atom. Electron affinities are measured in the gaseous state. In general, electron affinities become more negative as we move from left to right on the periodic table.
30 Ιαν 2023 · Unlike electronegativity, electron affinity is a quantitative measurement of the energy change that occurs when an electron is added to a neutral gas atom. The more negative the electron affinity value, the higher an atom's affinity for electrons. Periodic Table showing Electron Affinity Trend
