Verified step by step guidance1
Recall that subatomic particles include protons, neutrons, and electrons, each with characteristic electric charges.
Understand that the proton is a positively charged particle found in the nucleus of an atom.
Remember the standard charge values: electrons have a charge of -1, protons have a charge of +1, and neutrons have no charge (0).
Identify that the question asks specifically for the electric charge of a proton, which is known to be positive.
Conclude that the electric charge of a proton is +1 in the simplified model of subatomic particles.
