In an atom, which subatomic particle carries a negative charge?

• A. Proton
• B. Nucleus
• C. Neutron
• D. Electron

Answer: (D)

Verified step by step guidance

1. Recall that an atom is composed of three main subatomic particles: protons, neutrons, and electrons.
2. Understand the charge of each particle: protons carry a positive charge, neutrons have no charge (neutral), and electrons carry a negative charge.
3. Note that the nucleus of an atom contains protons and neutrons, but not electrons.
4. Since the question asks for the subatomic particle with a negative charge, focus on the particle outside the nucleus with a negative charge.
5. Identify the electron as the subatomic particle that carries a negative charge.
