Quarks can actually vary greatly in size.
The most common types of Quarks are Up and Down (scientists are not the most creative when it comes to names) and they have the mass of about 1/400 and 1/200 (respectfully) the mass of a proton. But some quarks, like the Top quark (another uncreative name) has the mass of the entire Tunston atom.
Three of them make a proton. So one is 1/3 the size of a proton.
Different quarks last different amounts of time, but all of the six quarks can only last on their own for small fractions of a second.
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.
There are 6 different types of quarks, named in pairs:Top, BottomStrange, CharmUp, Down0123qwerty0123But don't forget that all particles, besides force particles ( gravity-graviton, electromagnetism-photon, weak force-low guage boson, strong force-gluon ), have antimatter counterparts.Anti-top, Anti-bottomAnti-strange, Anti-charmAnti-up, Anti-down
While there are some hypothesis that quarks might be made up of smaller particles, there is no general consensus on this topic.
Neutrons consist of small particles, called "Quarks". Protons also consist of quarks, but what quarks is made of, is still not discovered.
Quarks and gluons
Different quarks last different amounts of time, but all of the six quarks can only last on their own for small fractions of a second.
Most of the times, quarks are described like point-like particles. So small, they're nearly just points in space
The subatomic particles found in protons and neutrons are quarks. There are two types of quarks that combine to make either particle, up and down quarks. Protons are 2 ups and a down and neutrons are 2 downs and an up.
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.
The small, negatively-charged particle in an atom is an electron. However, this is not in the nucleus. The small negative particles in the nucleus are down quarks, which are smaller than protons and electrons. Strange quarks and bottom quarks are also negative, but are not found in the nucleus.
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
