In the traditional cDFT formalism, the global derivatives of energy over N have been expressed in units of energy, typically in eV. This comes from the basic formulation of the electron density, hence also the number of electrons as dimensionless and this method makes the formalism clear. However, it has been noted by March that it leads to non-physical sign of the energy (+) while the binding energy of any system of electrons and nuclei is negative. The correction, by introducing the charge factor with the electron density: -𝑒𝜌(𝐫), had been proposed by March, following the earlier analysis by Feynman. The units of electric field . This method has been applied in presentation of the results of this work.
