Does electrons orbit the nucleus only because that they have unlike charges ?
That’s a very simplified view. Electrons don’t orbit nuclei, they sit at different energy levels based on their energy state. Their position is a factor of probability; they are in fact at all places in their energy level simultaneously. When they are measured this quatum waveform collapses and the electron appears in just one place. It’s hard to picture it, but think of atoms as like onions. Each skin is a different energy level, and the electrons are in every part of this level simultaneously. However, when the atom is observed (in the physical world) the electrons stop being in all places and resolve to just one place (waveform collapse).
