located in the nucleus, what is the overall charge of the nucleus portion of an atom:
positive, negative, or no charge at all? - answer The overall charge of the nucleus is
positive because the protons are positive and the neutrons have no charge.

have a negative charge, and the electrons are the only thing in the electron cloud, the
electron cloud has a negative charge.
