Final answer:
Protons have a positive charge, neutrons have no charge, and electrons have a negative charge.
Step-by-step explanation:
Protons have a positive charge of +1, while neutrons have no charge (neutral). Electrons have a negative charge of -1.
In uncharged, neutral atoms, the number of electrons orbiting the nucleus is equal to the number of protons inside the nucleus, resulting in an atom with no net charge.
It is worth noting that protons and neutrons both reside in the nucleus of an atom, while electrons orbit the nucleus.
