Since protons (p+) with a positive charge and neutrons (n0) without a charge are located in the nucleus, what is the overall charge of the nucleus portion of an atom: positive, negative, or no charge at all? Explain.

Positive

Explanation:

The nucleus of an atom has a net positive charge  which is balanced by the negative charge of the electrons residing in the orbital of an atom. The reason why the nucleus of an atom is positively charged is because it contains two sub atomic particles;

The protons and neutrons. In terms of charge, the proton is positively charged and the neutron is neutral. This means the neutron does not partake in the charge of the nucleus. Hence the net charge of the nucleus is decided by the protons which are positively charged
