Final answer:
Neon has three naturally occurring isotopes with different numbers of neutrons: Ne-20, Ne-21, and Ne-22.
Step-by-step explanation:
Neon does have multiple isotopes. According to the information provided, neon has three naturally occurring isotopes. The first isotope, Ne-20, has 10 neutrons and a mass of 19.99 amu. The second isotope, Ne-21, has 11 neutrons and a mass of 20.99 amu. The third isotope, Ne-22, has 12 neutrons and a mass of 21.99 amu. Therefore, the correct answer is A) Yes, neon has multiple isotopes.
