ນິວຕຣອນ (Neutron)250x250pxThe quark content of the neutron. The color assignment of individual quarks is arbitrary, but all three colors must be present. Forces between quarks are mediated by gluons.ການຈັດປະເພດBaryonອົງປະກອບ1 up quark, 2 down quarksສະຖິຕິFermionicຄອບຄົວHadronການໂຕ້ຕອບກາວິທັດ, ອ່ອນເພຍ, ແຂງແຮງ, ໄຟຟ້າສັນຍາລັກn, n0, N0AntiparticleAntineutronTheorizedErnest RutherfordErnest Rutherford Archived 2011-08-03 at the Wayback Machine.
