Every particle that should exist if quarks are real has been found.
No particle that should not exist if quarks are real has ever been found.
The results of in-elastic scattering between hadrons fits perfectly with quark.
The hypothesis of charm quarks predicted experimental results that were almost perfectly replicated with the discovery of the psi-particle.
In other words, the quark hypothesis matches observation perfectly.
That's about as strong of evidence as can exist.

Hadrons are composed of 3 quarks. Protons and neutrons are hadrons. The 2 types of quarks used in this instance are up quarks and down quarks. Yes, there are quarks in a nucleus.
Up quarks and down quarks are in protons and neutrons.
Quarks. There are three quarks in a proton.
3 they have 2 up quarks and 1 down quarks (yes its quarks not quarts) :D
electron has no quarks. both electrons and quarks are fundamental particles and are composed only of themselves.
There are no quarks in an electron. Electrons are leptons, which are not made of quarks. Further, the electron is a fundamental particle, just like the quark. That means that neither quarks or electrons are made up of other particles, per the Standard Model of particle physics.
In an atom, the neutrons and protons are made up of up quarks and down quarks. Strange quarks, charms quarks, top quarks, and bottom quarks also exist, but do not play as much of a role in the structure of an atom.
Hadrons are composed of 3 quarks. Protons and neutrons are hadrons. The 2 types of quarks used in this instance are up quarks and down quarks. Yes, there are quarks in a nucleus.
Quarks and anti-quarks
There are six quarks, the up, down, charm, strange, top, and bottom quarks.
Up quarks Down quarks Bottom quarks Top Quarks Charm quarks Strange Quarks and then there were leptons... simple- 8 protons 8 electrons 8 Neutrons and if you're dumb and you mean what is in air, then why don't you learn how to google
there are 7 quarks in aluminum
Up quarks and down quarks are in protons and neutrons.
Up quarks and down quarks are in protons and neutrons.
Since all protons and neutrons are made of quarks and they have mass, quarks must have mass (in fact they do).
Protons and neutrons are composite particles make up of up and down quarks. There are two up quarks and one down quark in a proton, and two down quarks and an up quark in a neutron.
Quarks. There are three quarks in a proton.
