Structural view of a proton with two up quarks (blue and red) and one down quark (green) and a neutron with one up quark (green) and two down quarks (red and blue).The forces between quarks are mediated by gluons. The proton is a subatomic particle with a positive electric charge of positive 1 and a mass slightly smaller than that of a neutron. The neutron has no electric charge. | |
