Final answer:
Protons carry a positive charge, electrons carry a negative charge, and neutrons have no charge. In neutral atoms, the number of protons and electrons are equal, resulting in an atom with no net charge.
Step-by-step explanation:
An atom's protons, neutrons, and electrons collectively influence the overall charge of an atom. Protons carry a positive charge, electrons carry a negative charge, and neutrons have no charge. In neutral atoms, the number of protons and electrons are equal, resulting in an atom with no net charge.
