The figure below is the plot of potential energy versus internuclear distance of molecule in the electronic ground state. The value of the net potential energy (as indicated in the figure) is for at which the electron-electron repulsion and the nucleus-nucleus repulsion energies are absent, find the value of to the nearest integer value.
As reference, the potential energy of atom is taken as zero when its electron and the nucleus are infinitely far apart.
Use Avogadro constant as Give an answer to the nearest integer value.
