Recall that the electric charge of a proton is a fundamental constant in chemistry and physics.
Understand that the charge of a proton is positive, while the charge of an electron is negative with the same magnitude.
Know the magnitude of the elementary charge, which is approximately \(1.602 \times 10^{-19}\) coulombs (C).
Since a proton has a positive charge, its charge is \(+1.602 \times 10^{-19}\) C.
Compare the given options to this value to identify the correct description of the proton's charge.
