What is Bottom quark?
'''Bottom quarks''' or '''beauty quarks''' are the second most [[Mass|massive]] of the [[elementary particle]]s ([[particle]]s that are so small that they can not be divided any more). All [[quark]]s are elementary particles. Bottom quarks have a [[Electromagnetism|charge]] of -1/3, similar to [[down quark]]s. Although bottom quarks are not very common, they are found in particles such as [[B meson]]s, among others. All bottom quarks will [[Radioactive decay|decay]] into [[charm quark]]s or [[up quark]]s in about 10<sup>–12</sup>, due to [[weak force]]. {{elementary}} [[Category:Quarks]]
