Which of the following statements about subatomic particles is true?

• A. Electrons are found in the nucleus along with protons and neutrons.
• B. Protons have no electric charge.
• C. Protons and neutrons have approximately the same mass, but electrons are much less massive.
• D. Neutrons carry a positive charge equal in magnitude to that of a proton.

Answer: (C)

Verified step by step guidance

1. Review the properties of subatomic particles: protons, neutrons, and electrons.
2. Recall that protons are positively charged particles located in the nucleus, while neutrons are neutral particles also found in the nucleus.
3. Understand that electrons are negatively charged particles that orbit the nucleus in electron clouds or shells, not inside the nucleus.
4. Compare the masses of protons, neutrons, and electrons: protons and neutrons have nearly the same mass, which is much greater than the mass of an electron.
5. Evaluate each statement based on these facts to determine which one is true.
