WebElectronegativity is a chemical property that describes the tendency of an atom or a functional group to attract electrons toward itself. The electronegativity of an atom is … Electronegativity, symbolized as χ, is the tendency for an atom of a given chemical element to attract shared electrons (or electron density) when forming a chemical bond. An atom's electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus. The higher the associated electronegativity, the more an atom or a su…
