Mass: the proton and neutron have about the same mass, which is roughly 1836 times that of the electron. Electric charge: the proton and electron are electrically charged, while the neutron is not. The proton and electron, however, are oppositely charged. Role in the atom: Protons and neutrons are closely bound together in the nucleus of an atom, while electrons are spread out around the nucleus. Particle type: Electrons are elementary particles called leptons (which do not couple to the strong nuclear force), while protons and neutrons are composite particles called hadrons, composed of quarks (which couple to the strong nuclear force). The proton and neutron are both composed of three quarks. The proton is composed of two up quarks and a down quark, while a neutron is composed of two down quarks and an up quark.
