: '''Leptons''' are [[Fundamental Particle|fundamental particles]] as they are not made of any smaller [[particle]]s.
: '''Leptons''' include:
:*[[Electron]] - A type of [[lepton]] with a [[mass]] of 9.11x10<sup>-31</sup> kg and a [[Electrical Charge|charge]] of -1.60x10<sup>-19</sup>[[Coulomb]]s.:*[[Muon]] - A type of [[lepton]] often referred to as a 'heavy electron' same [[Electrical Charge|charge]] as an [[electron]] (-1.60x10<sup>-19</sup>) [[Coulomb]]s but a [[mass]] 206 times the [[mass]] of an [[electron]].
:*[[Neutrino]] - A type of [[lepton]] with zero [[Electrical Charge|charge]] and negligible [[mass]].
: '''Leptons''' are affected by the:
:*[[Electromagnetic Interaction]]
:*[[Gravitational Interaction]]
