Which subatomic particle in an atom has no electric charge?

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

Answer: (C)

Verified step by step guidance

1. Recall that atoms are composed of three main subatomic particles: electrons, protons, and neutrons.
2. Understand the electric charge of each particle: electrons have a negative charge, protons have a positive charge, and neutrons have no charge.
3. Identify that the question asks for the particle with no electric charge.
4. Recognize that the neutron is the subatomic particle with no electric charge, making it electrically neutral.
5. Confirm that the correct answer is neutron, as electrons and protons carry negative and positive charges respectively, and positrons are positively charged particles (antiparticles of electrons).
