WebNov 26, 2024 · Electron affinities are more difficult to measure than ionization energies. An atom of Krypton in the gas phase, for example, gives off energy when it gains an electron to form an ion of Krypton. Kr + e – → Kr – – ∆H = Affinity = — kJ/mol. Electron affinity is one of the most important parameters that guide chemical reactivity. WebDec 30, 2024 · The definition of electronegativity is: The tendency of an atom to attract electrons to form a chemical bond. The electronegativity of an atom depends upon its atomic number and its atomic radius, which means that the more the distance between the nucleus and its valence electrons, the lower the electronegativity and vice versa.Electronegativity …
