The quarks, leptons, and gauge bosons are elementary particles.
Protons are spin-1/2 fermions and are composed of three quarks making them baryons. The two up quarks and one down quark of the proton are also held together by the strong nuclear force, mediated by gluons. The neutron is a subatomic particle with no net electric charge and a mass of 939.573 MeV/c² (1.6749 × 10−27 kg, slightly more than a proton). Its spin is ½.
Protons and neutrons are both nucleons, which may be bound by the nuclear force into atomic nuclei.
The electron is a fundamental subatomic particle that carries a negative electric charge. It is a spin-½ lepton that participates in electromagnetic interactions, and its mass is less than one thousandth of that of the smallest atom.

An element consists of atoms, which are made up of neutrons, positive protons (both in the nucleus) and negative electrons (in a surrounding shell). These, in turn are made up of sub-atomic particles called quarks.
An element consists of the same types of atoms, sometimes on their own, as in helium, sometimes as a pair, as in hydrogen, or in a lattice formation (eg carbon and the metals).

Protons, Neutrons and electrons.
Protons and Neutrons are in the nucleus of an atom and electrons revolve around the nucleus.
