The correct statement is: **Their atomic masses differ.**
Explanation:
- Neon has three stable isotopes: neon-20, neon-21, and neon-22. Each of these isotopes has a different number of neutrons, which results in different atomic masses.
- The number of protons in all isotopes of neon is the same (10 protons), which means that the statement "Their number of protons differ" is false.
- The statement "They are radioactive, like all isotopes" is also false because neon-20, neon-21, and neon-22 are stable isotopes.
- Therefore, the only true statement is that their atomic masses differ.
