Fixed typo, mentioned composite and fundamental particles
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.
A '''subatomic particle''' is any particle that is smaller than or makes up an [[atom]]. There are two types of sub-atomic particle: composite particles, which include [[protons]], and [[fundamental particles]], which include [[electrons]]. At one time this included [[protons]], [[neutrons]], and [[electron]]s, which are known to make up all elements (except ordinary [[hydrogen]] whoch does not contain any neutrons in its nucleus). 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 exist are [[photons]] and [[neutrinos]].

Subatomic particles are categorized into:
Subatomic particles are categorized into:
*[[Fermion]]s, which include [[lepton]]s ([[electron]]s and [[neutrino]]s) and [[hadron]]s (such as [[proton]]s and [[neutron]]s).
*[[Fermion]]s are "matter" particles, 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 (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).
*[[Boson]]s are "force carriers", 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 [[higgs 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.
