→About Fermions
===Meaning===
'''Fermions''' are a group of [[Subatomic Particle|subatomic particles]] which are not able to exist in the same place at the same time as one another.
''NB: This definition is loose and inaccurate, but sufficient at this stage. It is more accurate to state that they are 'half-integer spin' and unable to have the same 'quantum state' as one another.''
===About Fermions===
: [[Subatomic Particle|Subatomic particles]] are divided into two major categories; '''fermions''' and '''bosons''[[boson]]s. [[Boson]]s, in contrast to '''fermions''', can exist in the same place at the same time as one another.
: The [[fermion]]s include:
:*[[Lepton]]s - A group of [[Fundamental Particle|fundamental particles]]
:**[[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]].
:*[[Quark]]s - A group of [[Subatomic Particle|subatomic particles]] believed to be [[Fundamental Particle|fundamental]] but have never been observed on their own. They always exists in either a triplet of [[quark]]s or a [[quark]]-[[antiquark]] pair.(''NB: A [[quark]]-[[antiquark]] pair known as a [[meson]] is a type of [[boson]].'')
:*[[Hadron]]s - [[Subatomic Particle|Subatomic particles]] made of [[quark]]s.
:**[[Baryon]]s - A type of [[hadron]] made of 3 [[quark]]s.
:***[[Proton]] - A type of [[baryon]] with a [[mass]] of 1.67x10<sup>-27</sup> kg and a [[Electrical Charge|charge]] of 1.60x10<sup>-19</sup>[[Coulomb]]s, made of 2 [[Up-quark]]s and 1 [[Down-quark]].:***[[Neutron]] - A type of [[baryon]] with a [[mass]] of 1.67x10<sup>-27</sup> kg and zero [[Electrical Charge|charge]], made of 2 [[Down-quark]]s and 1 [[Up-quark]].
