Within the theoretical framework of the Standard Model for particle physics, a neutron comprises two down quarks with charge and one up quark with charge . The neutron is therefore a composite particle classified as a hadron. The neutron is also classified as a baryon, because it is composed of three valence quarks. The finite size of the neutron and its magnetic moment both indicate that the neutron is a composite, rather than elementary, particle.
