Electron affinity by element
Webelectron affinityThe electron affinity of an atom or molecule is defined as the amount of energy released when an electron is added to a neutral atom or molecule to form a negative ion. electronegativityThe tendency of an atom or molecule to attract electrons to itself. WebThe electron affinity (E ea) of a neutral atom or molecule is defined as the amount of energy released when an electron is added to it to form a negative ion. This can be shown for the chloride ion formation below: Cl + e− → Cl − + energy Generally, nonmetals have a more positive electron affinity than metals.

WebDec 30, 2024 · Electronegativity and electron affinity are two different chemical properties of elements. Electronegativity refers to the ability of an atom to attract electrons to form a chemical bond. Whereas electron affinity is the amount of energy released once that chemical bond is formed between the atoms.
