Which subatomic particle has a negative charge and is found outside the nucleus?

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

Answer: (D)

Verified step by step guidance

1. Recall the three main subatomic particles: protons, neutrons, and electrons.
2. Understand the charge of each particle: protons have a positive charge, neutrons have no charge (neutral), and electrons have a negative charge.
3. Identify the location of each particle: protons and neutrons are located inside the nucleus, while electrons are found outside the nucleus in electron clouds or orbitals.
4. Since the question asks for a negatively charged particle found outside the nucleus, focus on the electron.
5. Conclude that the electron is the subatomic particle with a negative charge located outside the nucleus.
