'''Carbon-12''' (also written <sup>12</sup>C) is an [[isotope]] of [[carbon]]. It is the most common isotope of carbon, as 98.89% of all carbon is this type of carbon. It is one of two stable (non-[[radioactive]]) isotopes of carbon. The other is [[carbon-13]]. Carbon-12 is important in [[chemistry]] as it is the benchmark from which all other [[relative atomic mass]]es are worked out. Its relative atomic mass is exactly 12. == Related pages == * [[Avogadro constant]] {{chem-stub}} [[Category:Isotopes]] [[Category:Carbon]]
