Which subatomic particle has a positive charge in the nucleus?

Which subatomic particle has a positive charge in the nucleus?

• A. Neutron
• B. Proton
• C. Electron
• D. Valence electron

Answer: (B)

In atoms, the nucleus contains protons and neutrons, while electrons orbit outside the nucleus. Protons carry a positive electric charge, neutrons have no charge, and electrons carry a negative charge. Because the question asks which subatomic particle has a positive charge in the nucleus, the answer is the proton. Protons provide the positive charge and most of the nucleus’s mass, whereas electrons and valence electrons are outside the nucleus and carry negative charge. Neutrons contribute mass but are neutral.
