Charge repellant behaviour

In a large part of chemistry atomic nuclei are considered mainly as massive point-like centres of positive charge, which attract the surrounding electrons and repel other nuclei. The attractive and repulsive Coulomb interactions between the constituting particles, i.e., nuclei and electrons, as well as their kinetic energy, must be balanced if stable molecular structures are to be formed. The application of quantum mechanics to describe the behaviour of electrons and nuclei under these interactions finally leads — in connection with structure optimization according to the energy minimiza-... 

It is easy to guess roughly what the behaviour of this system will be. If the protons are anywhere near each other, the electron will be attracted by both protons and will describe some orbit about them. The protons, each with a mass 1840 times the mass of the electron, will be relatively sluggish in responding to the pull of the rapidly moving electron. But if the electron spends more time between than away from them, it will pull them toward each other on the average. As they approach each other, their positive charges will repel each other more and more, and furthermore the electron...
