Highest to lowest electron affinity
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 atom. Web8 de mai. de 2024 · Electronegativity is defined as the ability of an atom in a particular molecule to attract electrons to itself. The greater the value, the greater the attractiveness for electrons. Electronegativity is a function of: (1) the atom's ionization energy (how strongly the atom holds on to its own electrons) and (2) the atom's electron affinity (how ...
