검증된 단계별 안내1
Recall that a proton is a subatomic particle found in the nucleus of an atom.
Understand that the charge of a proton is a fundamental property and is always positive.
Recognize that the magnitude of the proton's charge is equal to the elementary charge, which is +1 in atomic charge units.
Compare the given options: Neutral (0), Double positive (+2), Negative (-1), and Positive (+1).
Conclude that the correct description of a proton's charge is Positive (+1) because it carries a single positive elementary charge.
