: *[[Baryon]]s are part of the larger family of [[particle]]s called [[hadron]]s, which are composed of [[quark]]s held together by the [[Strong Nuclear Interaction|strong force]].*'''Baryons''' include::**[[Proton]] - A type of [[baryon]] with a [[mass]] of 1.67x10^-27kg and a [[Electrical Charge|charge]] of 1.60x10^-19 [[Coulomb]]s, made of 2 [[Up-quark]]s and 1 [[Down-quark]].:**[[Neutron]] - A type of [[baryon]] with a [[mass]] of 1.67x10^-27kg and zero [[Electrical Charge|charge]], made of 2 [[Down-quark]]s and 1 [[Up-quark]].: *There are many other [[baryon]]s made from different groups of [[quark]]s. However, these are unstable and exist only for very short periods of time before [[Radioactive Decay|decaying]] via the [[Weak Nuclear Interaction|weak nuclear interaction]] into other, most stable, [[Subatomic Particle|subatomic particles]].
