Proton

"'a small, small thing. Has a positive electric charge.' -ICantEdit"Protons are a kind of nucleon that contains one down quark and two up quarks, and these quarks are held together by gluons. Protons are almost always found within atoms, and they have a positive charge. The other kind of nucleon, called a neutron, are usually found near them as well. Protons are slightly larger in size, but also slightly less massive in mass, in comparison to Neutrons.
