They are very dense
3 they have 2 up quarks and 1 down quarks (yes its quarks not quarts) :D
The nucleus of an atom is made up of two types of subatomic particles, protons and neutrons which together are sometimes called nucleons. These subatomic particles are in turn made up of smaller particles called quarks.
Electrons hold a negative charge while neutrons are neutral and protons are positive. Electrons are leptons having no internal structure (leptons are generally believed to be point particles, having zero volume), protons and neutrons are baryons composed of three quarks (leptons) with a measurable volume.
The weight of an atom is primarily determined by the total number of protons and neutrons in its nucleus. Electrons, which have negligible mass, also contribute to the atom's weight but to a much smaller extent.
protons and neutrons in the nucleus. It is calculated by adding the number of protons and neutrons in an atom. Electrons do not significantly contribute to the atomic mass due to their much smaller mass compared to protons and neutrons.
Quarks have not been observed to exist separately - they are "confined" within larger particles such as protons and neutrons, that are made up of several quarks (3 each, in the case of protons and neutrons).
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.
Electrons are fundamental particles and we can not actually measure the size of an electron (we know we will NEVER be able to). However the size of protons and neutrons can be measured and we know that these particles are made up of other, more fundamental particles which are probably smaller.
All elements are made of protons, neutrons, and electrons. An atom of an element has the same number of electrons as it does protons in it's neutral state. Different elements have a different number of protons. Atoms of the same element can have a different number of neutrons however, and these are known as isotopes.
The strong force is found within the atomic nucleus, holding protons and neutrons together. It is mediated by particles called gluons and is responsible for binding quarks together to form particles such as protons and neutrons.
Protons and neutrons are in atomic nuclei, while electrons are located outside atomic nuclei in various probabilities of energetically favored states. Quarks are the fundamental particles that compose the hadron family of particles, of which protons and neutrons are members. Thus, you better believe quarks are found in atomic nuclei! In fact, because of the way the strong nuclear force acts on quarks, they can never be found on their own they are not found on their own at low energies but it is possible that they can become free at extremely high energies, as is the case in the hypothetical quark-gluon plasma. As we can observe them, however, they're always in protons and neutrons (or the various other hadrons).

There are quarks in the nucleus of an atom, but they are found there because quarks make up protons and neutrons which make up atomic nuclei. They (quarks) do not have "individual identities" in the nucleus of an atom, but are elementary particles that are the building blocks of composite particles called hadrons. Quarks are never found in isolation anywhere.

Nuclear force- it is a force that exists between two or more nucleons, it is responsible for the bonding of the neutrons and protons. The reason itself is much more complicated because it involves quarks which are smaller than protons or neutrons.
The proton is slightly less massive.
