Recall that the electric charge of subatomic particles is a fundamental property: protons, neutrons, and electrons each have characteristic charges.
Understand that a proton carries a positive electric charge, which is the basic unit of positive charge in chemistry and physics.
Recognize that the magnitude of the proton's charge is equal to the magnitude of the electron's charge but opposite in sign.
Note that the proton's charge is not double positive (+2), neutral (0), or negative (-1), but rather a single positive charge (+1).
Therefore, the best description of the electric charge of a proton is Positive (+1).
