Question

Quizplus · Accepted Answer

An atom consists of a nucleus (made up of protons and neutrons) and electrons. Electrons have a mass that is approximately 1/1836 of the mass of a proton. Nucleus is a general term that refers to the center of an atom, which consists of both protons and neutrons. Quarks are subatomic particles that make up protons and neutrons. Therefore, the particle with a mass approximately equal to the mass of a proton is a neutron.
