This can be answered by observation and physics:
High energy collisions break protons and neutrons into their constituent quarks.
Protons and neutrons are hadrons; they are made of quarks. Protons are composed of two up quarks and a down quark, while neutrons are composed of one up quark and two down quarks. The quarks are held together by gluons. Electrons are not composed of more fundamental particles; they are categorized as leptons.they are made up of quarks
Atomic nuclei....Protons contain two up quarks and a down quark orbiting each other, and neutrons contain two down quarks and an up quark.
Protons and neutrons contain different types of quarks and gluons.
The quark has a neutron and proton stuck on it in the nucleus, which is related to the isotope. But for the subatomic particle, it is in it! All quarks are subatomic particles but not all subatomic particles are quarks
Any particle that is not a hadron does not contain quarks. Fundamental bosons and leptons are the only category of particles that do not contain quarks.
Protons and neutrons contain quarks.
High energy collisions break protons and neutrons into their constituent quarks.
A proton contain 2 up quarks and 1 down quark; quarks are bonded by gluons.
Protons contain two up quarks and one down quark, while a neutron contains two down quarks and one up quark.
Protons and neutrons are hadrons; they are made of quarks. Protons are composed of two up quarks and a down quark, while neutrons are composed of one up quark and two down quarks. The quarks are held together by gluons. Electrons are not composed of more fundamental particles; they are categorized as leptons.they are made up of quarks
The atomic nucleus contains protons and neutrons, which themselves each contain three quarks. The protons and neutrons are held together by continually exchanging virtual mesons, which contain two quarks. The quarks are held together by continually exchanging virtual gluons.
The nucleus of an atom contain protons and neutrons; protons and neutrons contain quarks and gluons.
Atoms contain protons, neutrons and electrons.Protons and neutrons contain quarks and gluons.
An atom contain protons, neutrons and electrons; protons and neutrons contain quarks and gluons.
Atomic nucleus contain neutrons and protons; and both contain quarks and gluons.
An atom contain protons, neutrons and electrons; protons and neutrons contain quarks and gluons.
