In the framework of the density functional theory a new electronegativity formulation via the Feynman-Kleinert path integral formalism in the markovian limit is proposed. The computation of the electronic density follows, in terms of partition function, the same procedure of the Levy constrained-search for the wave function. The obtained electronegativity scale seems to respect the main criteria largely used for its acceptability.
