Which subatomic particle has no electrical charge?

Which subatomic particle has no electrical charge?

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

Answer: (C)

Studying how electrical charge works at the subatomic level, you learn that protons carry a positive charge, electrons carry a negative charge, and neutrons have no net charge at all. Neutrons sit in the nucleus with protons, contributing to mass and nuclear stability, but they don’t contribute to the atom’s overall electric charge. This is why neutrons are described as neutral. The other common particles carry charge: protons are positively charged, electrons are negatively charged, and a positron has a positive charge like a proton (it's the antimatter counterpart of the electron). So none of those are neutral, which helps explain why the neutron is the correct pick.
