Final answer:
The overall charge of the nucleus is positive because protons carry a positive charge, while neutrons have no charge. The positive charge of the protons outweighs the neutral charge of the neutrons, resulting in an overall positive charge.
Step-by-step explanation:
The overall charge of the nucleus is positive. This is because the protons, which carry a positive charge, are located in the nucleus of an atom. Neutrons, on the other hand, are uncharged and have no charge. The positive charge of the protons in the nucleus outweighs the neutral charge of the neutrons, resulting in an overall positive charge.
