Protons are one of the two types of subatomic particles that form in the nucleus of an atom (together with neutrons).[1]
A proton is made up of two up quarks and one down quark. According to the Standard Model of particle physics, quarks are fundamental particles, meaning that they cannot be split into smaller particles.[2]
