검증된 단계별 안내1
Recall the three main subatomic particles in an atom: protons, neutrons, and electrons.
Understand the charge of each particle: protons have a positive charge, neutrons have no charge (neutral), and electrons have a negative charge.
Identify that the question asks specifically for the subatomic particle with a negative charge.
Recognize that among the options given (Neutron, Proton, Electron, Nucleus), only the electron carries a negative charge.
Note that the nucleus is not a particle but the central part of the atom containing protons and neutrons, so it does not itself have a charge.
