Which subatomic particle in an atom carries a positive charge?

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

Answer: (A)

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, electrons carry a negative charge, and neutrons have no charge (they are neutral).
3. Recognize that protons and neutrons are located in the nucleus of the atom, while electrons orbit around the nucleus.
4. Identify that the particle with a positive charge is the proton.
5. Conclude that the correct answer to the question is the proton, as it is the subatomic particle that carries a positive charge.
