Verified step by step guidance1
Recall that the electric charge of subatomic particles is a fundamental property that determines how they interact electrically.
Identify the three main subatomic particles: protons, neutrons, and electrons.
Remember that protons carry a positive charge, electrons carry a negative charge, and neutrons are neutral (no charge).
Specifically, the charge of a proton is defined as +1 elementary charge, which is the basic unit of positive charge.
Therefore, the best description of the electric charge of a proton is Positive (+1).
