Which subatomic particle has no electric charge?

Which subatomic particle has no electric charge?

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

Answer: (A)

Electric charge tells us whether a particle is positively charged, negatively charged, or neutral. The particle with no electric charge is neutral, meaning its charge is zero. This is the neutron. Neutrons sit in the nucleus with protons and contribute to the atom’s mass and nuclear stability without adding any charge. Protons carry a positive charge, electrons carry a negative charge, and a positron carries a positive charge as the antimatter counterpart of the electron. So neutrons are the only particle listed that has no electric charge.
