Hi Van!,Good afternoon!I have a question: why electrons which revolve around the nucleus dont repel each other? It is rule that like charges repel each other.

The electrons in atoms do repel each other. That's why atoms typically only pick up enough electrons to balance the charge of the nucleus, giving a neutral atom. The next electron would see an overall neutral object, and only be weakly attracted to the extent that the other electrons rearrange their distributions a little to make an electric dipole. That repulsion also makes it complicated to calculate the energies of different states of the atom.
