Which of the following statements about subatomic particles is true?

• A. Neutrons carry a positive charge.
• B. Protons are found outside the nucleus.
• C. Protons and neutrons have approximately the same mass.
• D. Electrons have a greater mass than neutrons.

Answer: (C)

Verified step by step guidance

1. Review the basic properties of subatomic particles: protons, neutrons, and electrons.
2. Recall that protons carry a positive charge, neutrons are neutral (no charge), and electrons carry a negative charge.
3. Understand the location of these particles: protons and neutrons are located inside the nucleus, while electrons orbit around the nucleus.
4. Compare the masses of these particles: 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.
