What is Composite particle?
'''Composite particles''' are [[subatomic particle]]s that are made of more than one [[quark]]. Simple [[particle]]s like [[proton]]s are actually composites of multiple quarks. Protons are known as [[baryon]]s, which means that they are made of exactly three quarks. Baryons are in a family called [[Hadron]]s, which simply means that they are made of quarks. The only other subcategory of Hadrons is [[Meson]]s, which are made of one quark and one [[Antiparticle|antiquark]]. Since they are made of [[quark]]s, composite particles are not so much hard balls, but rather like clouds that contain these quarks. Depending on the [[Kinetic energy|energy]] contained by the quarks, the quarks of a proton vibrate, and this gives a proton a size larger than the actual size of the three quarks combined. {{Elementary}} For more information see: [[:en:Subatomic_particle|subatomic particles]], [[:en:Elementary_particle|elementary particles]], and the composite particles on the [[:en:List_of_particles#Composite_particles|'List of particles']] wiki pages. {{physics-stub}} [[Category:Subatomic particles]] [[en:List of particles#Composite particles]]
