Which subatomic particle is positively charged and resides in the nucleus?

• A. Electrons
• B. Protons
• C. Neutrons
• D. Quarks

Answer: (B)

In atoms, the nucleus contains the particles that contribute to mass and the overall positive or neutral charge. The particle that is positively charged and stays in the nucleus is the proton. Protons carry a positive electric charge and live at the center of the atom, often alongside neutrons. Neutrons are also in the nucleus but have no charge. Electrons, by contrast, are negatively charged and occupy regions around the nucleus called electron clouds. Quarks are the smaller particles that make up protons and neutrons, not the distinct charged particle you find orbiting or sitting in the nucleus by themselves. So the positively charged particle residing in the nucleus is the proton.
