Recall that the proton is a subatomic particle found in the nucleus of an atom.
Understand that the proton carries a positive electric charge, which is fundamental to the structure of atoms.
Know that the magnitude of the proton's charge is defined as +1 elementary charge, which is the standard unit of electric charge.
Compare the given options to the known charge of a proton: +1, +2, -1, and 0.
Conclude that the correct description of the proton's relative charge is +1, as it carries one positive elementary charge.
