Question

Quizplus · Accepted Answer

An atom is structured with negatively charged electrons orbiting around a small, dense nucleus that contains positively charged protons and neutral neutrons. This description matches choice A, where the nucleus is positively charged (due to protons) and very massive compared to the electrons, which are negatively charged and move around the nucleus.
