Electronegativity is the chemical reaction that defines the inclination of an atom or a functional group to attract electrons to itself. The electronegativity of an atom is affected by both its atomic number and the distance at which the valence electrons reside from the charged nuclei.The electropositive element refers to the atom's tendency to lose e− and to form a positive ion. Electronegativity of the element is the ability to attract a shared e-to molecule f
