Which subatomic particle has a positive charge and is located in the nucleus of an atom?

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

Answer: (B)

Verified step by step guidance

1. Recall the three main subatomic particles in an atom: protons, neutrons, and electrons.
2. Understand the charge of each particle: protons have a positive charge, electrons have a negative charge, and neutrons have no charge (neutral).
3. Identify the location of each particle within the atom: protons and neutrons are located in the nucleus, while electrons orbit around the nucleus.
4. Since the question asks for a positively charged particle located in the nucleus, focus on particles in the nucleus with positive charge.
5. Conclude that the proton is the subatomic particle with a positive charge located in the nucleus of an atom.
