Which subatomic particle in an atom carries a negative charge?

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

Answer: (B)

Verified step by step guidance

1. Recall that an atom consists of three main subatomic particles: protons, neutrons, and electrons.
2. Understand the charges associated with each particle: protons carry a positive charge, neutrons have no charge (neutral), and electrons carry a negative charge.
3. Identify the location of each particle: protons and neutrons are located in the nucleus, while electrons orbit the nucleus in electron clouds or shells.
4. Since the question asks for the subatomic particle with a negative charge, focus on the particle known to have a negative charge, which is the electron.
5. Conclude that the electron is the subatomic particle in an atom that carries a negative charge.
