What is the charge of a proton?

Explanation:
Protons have a positive electric charge. This positive charge is the same for every proton, equal in magnitude to one elementary charge. Isotopes differ only in the number of neutrons, not in the number of protons, so the charge of a proton is not changed by which isotope you have. In atoms, protons (positive) balance with electrons (negative) to give neutral atoms when the numbers are equal, while neutrons are electrically neutral. So the correct idea is that a proton is positively charged.
