electron affinity (plural electron affinities)
(physics) The energy released when an electron is attached to an atom or molecule; used as a measure of its ability to form an anion
Furthermore, silver's Pauling electronegativity of 1.93 is higher than that of lead (1.87), and its electron affinity of 125.6 kJ/mol is much higher than that of hydrogen (72.8 kJ/mol) and not much less than that of oxygen (141.0 kJ/mol). Source: Internet
Chlorine has the highest electron affinity and the third highest electronegativity of all the reactive elements. Source: Internet
A trend of decreasing electron affinity going down groups would be expected. Source: Internet
A uniform decrease in electron affinity only applies to group 1 atoms. Source: Internet
Huheey, Keiter & Keiter, pp. 42, 880–81 Metallic character The lower the values of ionization energy, electronegativity and electron affinity, the more metallic character the element has. Source: Internet
In this particular example, the electron binding energy has the same magnitude as the electron affinity for the neutral chlorine atom. Source: Internet
