C) nucleons.
D) nuclides.

Question

Quizplus · Accepted Answer

Isotopes of a given element have the same number of protons (i.e., the same atomic number), but different numbers of neutrons (i.e., different mass numbers). Therefore, option A is the correct answer. Option B is incorrect because isotopes have different numbers of neutrons. Option C is not technically incorrect, but it is not the best choice because nucleons refer to both protons and neutrons. Option D is incorrect because nuclides refer to specific types of atoms and their isotopes.
