Quizplus · Accepted Answer

A neutron has no charge and its mass is approximately the same as that of a proton. This makes them both slightly more massive than electrons. Neutrons contribute to the mass of an atom, but not to its charge, as they have no electric charge. Therefore, option C is the correct characterization of a neutron.
