Multi-Electron Atoms

[Helen Mejia 1I]

Hi, can someone please explain multi-electron atoms and electrostatic (coulomb) potential energy?
I did not understand today's lecture at all.

[Cecilia Jardon 1I]

From what I understood, it is about 2 specific concepts 1) Magnitude of the charge 2) distance b/w them q1 : charge 1 and q2: charge 2 and r is the distance b/w the charges.

Multi electron atoms are all the atoms except for hydrogen, which only has one electron. Multi electron atoms are more complex because of the reactions that multiple electrons have with each other that effect electron energy. For example, in multi electron atoms, there is something called electron shielding where electrons in outer energy levels are shielded from the nucleus by inner electron which reduces electrostatic attraction. All in all, multi electron atoms are just atoms besides hydrogen that have electrons in higher orbitals. These atoms have additional factors that affect electron energy.
