Coulomb inverse square law

Long-range coulombic interactions, i.e. those acting over long distances between the ions. These are electrostatic interactions obeying the Coulomb inverse square law (Section 10.4.2). 

The structure of the entire system of the chemical elements is explicable on the following basis the interactions between nucleus and electrons are according to the Coulomb inverse square law the electrons of an atom are assigned one after another to various energy levels with the succession of quantum numbers required by the wave equation and by the Pauli principle.
