Electronegativity is a mnemonic number for an atom in a molecule for expressing its ability to attract or hold the electron in diatomic or poly atomic system. This number is either used for energy (a quantum-mechanical entity) or for Force (non-quantum entity). In this article, a plethora of electronegativity models are revisited .A theoretical equation for Electronegativity in terms of Hellmann-Feynman Force or Ehrenfest Force is a special feature of this article .Electronegativity values are computed for various elements using numerical values of energy obtained through Hatree-Fock-Rothan calculation , effective nuclear charge and most probable radius .
