Which subatomic particle is located in the nucleus and has no electric charge?

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

Answer: (C)

Inside the nucleus, the particles are protons and neutrons. The one that has no electric charge is the neutron. Neutrons sit in the nucleus along with protons and contribute to the atom’s mass and stability, helping hold the nucleus together through the strong nuclear force. Protons, on the other hand, are positively charged, and electrons are outside the nucleus in orbit around it and carry negative charge. An ion is not a single nuclear particle; it’s an atom that has a net electric charge due to gaining or losing electrons.
