Forces between subatomic particles in a molecule

[Frigus]

I was seeing a video about molecular orbital theory..at t=3:56 he counted the forces but I don't why he didn't considered repulsions between electrons.
Please can you tell me why he didn't considered repulsions?

He looks at the forces on the H nuclei, the protons. It's those that are being pulled together by the electrons 'preferably moving about' in the area between them.

Your gut feeling is right, but it applies to the electron orbitals, not to the proton 'positions'.

Got it!
