<b>Electronegativity A Force or Energy</b> Electronegativity as force or energy leads to new ansatz at critical point in binding or bonding state in between two similar atoms or dissimilar atoms. Electronegativity as a quantum mechanical entity energy or non quantum entity force is yet to be answered. The dual approach to electronegativity has been discussed in this paper. The aim of this paper is to prove that Electronegativity as Hellman Feynman Force is more accurate and absolute. Electronegativity has been computed using the Hartree Fock and Rothan Hrtree Fock energy equations and equivalent electrostatic force equation.
