'''Fermions''' are [[subatomic particle]]s with half-[[integer]] spin that obey the [[Jacques Dirac|Dirac]]-[[Enrico Fermi|Fermi]] statistics. The known elementary fermions are [[quark]]s and [[lepton]]s, which make up all [[atom]]s. Composite particles, such as [[meson]]s, can also be fermions. | '''Fermions''' are [[subatomic particle]]s with half-[[integer]] spin that obey the [[Jacques Dirac|Dirac]]-[[Enrico Fermi|Fermi]] statistics.
