A '''subatomic particle''' is any particle that is smaller than or makes up an [[atom]].  At one time this included [[protons]], [[neutrons]], and [[electron]]s, which are known to make up all elements (except ordinary [[hydrogen]] does not have any neutrons).  Since that time additional particles have been experimentally detected or theorized.  These include [[quarks]] and [[gluons]] which are a level smaller still.

Other particles that are believed to exist are [[photons]] and [[neutrinos]].

Most of space on the subatomic level is empty, with only very small amounts having particles in them.

Subatomic particles are categorized into:

Subatomic particles are categorized into:

*[[Fermion]]s, which include [[lepton]]s and  [[hadron]]s (such as [[proton]]s and [[neutron]]s).

*[[Fermion]]s, which include [[lepton]]s ([[electron]]s and [[neutrino]]s) and  [[hadron]]s (such as [[proton]]s and [[neutron]]s).

*[[Boson]]s, which include [[photon]]s.

*[[Boson]]s, which include [[photon]]s (responsible for the electromagnetic interaction), [[gluons]] (responsible for the string nuclear force), the w and z bosons (responsible for the [[weak force|weak nuclear force]] and the [[highs boson]] (responsible for mass).

 

The [[graviton]] is a [[boson]] theorised by some models and would be responsible for gravitation. It has so far not been detected.
