How many quarks are in a proton? How many quarks are in a neutron? Protons and neutrons each contain three quarks. A proton is composed of two 'Up' quarks and one 'Down' quark while neutrons are composed of one 'Up' quark and two 'Down' quarks.

The up quark (charge 2 / 3 e) and down quark (charge â 1 / 3 e) make up protons and neutrons and are thus the ones observed in ordinary matter. Strange quarks (charge â 1 / 3 e) occur as components of K mesons and various other extremely short-lived subatomic particles that were first observed in cosmic rays but that play no part in ordinary matter.
