Question

Quizplus · Accepted Answer

Protons and neutrons are both found in the nucleus of an atom. Electrons, which are negatively charged, orbit the nucleus in energy shells. Therefore, (B) is incorrect because neutrons accompany protons in the nucleus, and (C) is incorrect because electrons orbit the nucleus rather than reside within it. Finally, (D) is also incorrect due to the absence of neutrons in the proposed arrangement.
