Which particle is neutrally charged in atomic nuclei?

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

Answer: (C)

Neutrons are the neutral members of the nucleus. They carry no electric charge, so they add mass and help hold the nucleus together without adding any repulsive electrical force. Protons, on the other hand, are positively charged and reside in the nucleus, contributing to the overall charge. Electrons orbit outside the nucleus and carry negative charge, while positrons are positively charged antiparticles not found in the nucleus. So the particle that is neutrally charged in atomic nuclei is the neutron.
