Quizplus · Accepted Answer

The nucleus of an atom contains all of the protons and neutrons in the atom. Electrons orbit the nucleus in shells. Therefore, option A and C are incorrect. Option D is incorrect because if an atom only contained neutrons in the nucleus, it would not have any charge and the electrons would not be held in orbit around it. Option E is incorrect because an atom also contains neutrons in the nucleus, not just protons.
