### Multi electron atoms

in the Q1Q2/r equation, what is this equation called and how are the two charges found?

This equation is known as the electrostatic potential energy of two charges. It is the energy needed to move a charge against its electrical field, in this case, the charge of the particles you are working with.

### Re: Multi electron atoms

the Q1 and Q2 are both charges and the R is the distance between the two charges. I'm pretty sure we'd be given enough information in the question to solve for all variables if we were asked to solve a question like this.

That equation is known as coulombs law. I think we won't be doing calculations involving it, but instead understanding how it relates to concepts within an atom.

This equation is actually not Coulomb's law. Coulomb's law is applied when finding the force of attraction or repulsion between electrons (F=k*Q1*Q2 / r^2). Although it may derive or relate to Coulomb's law, Q1*Q2 / r measures the electrostatic potential energy of the electrons, not their forces.
