검증된 단계별 안내1
Recall the basic properties of subatomic particles: protons, neutrons, and electrons.
Understand that protons are one of the three main subatomic particles found in an atom's nucleus.
Remember that the electric charge of a proton is a fundamental property and does not change depending on the atom.
Know that the proton carries a positive electric charge, which is denoted as \(+1e\), where \(e\) is the elementary charge.
Contrast this with electrons, which have a negative charge, and neutrons, which have no charge (neutral).
