### Coulombic potential energy

How do you write an expression for total coulombic potential energy and what does total coulombic potential energy mean?

### Re: Coulombic potential energy

V=(kq1q2)/d
V=Potential Energy
k=Positive-valued proportionality constant
q1=charge on particle 1 (positive proton or negative electron)
q2=charge on particle 2 (positive proton or negative electron)
d=distance between particles

Also, sometimes when referencing the distance between the charges, "d" is notated instead by "r". In short, for multi Electron atoms, there are additional factors that effect e- energy, one of them being the electrostatic potential energy (coulomb) between two charges. These charges interact with each other and cause different electrostatic interactions between the nucleus and e- when e- is in different orbitals.
