The proton is a particle with a positive electric charge that is in the nucleus of atoms. It is a particle that is made of other particles and belongs to the baryon family. That means that it contains 3 different colored quarks. The proton is made of 2 up quarks and a down quark. Here you see Ushi (up quark), Danny (down quark) and Harold (up quark) in their proton Subatomic Universe Vehicle (SUV).
