WebApr 7, 2015 · Carbon-13 is slightly different from carbon-12, the more abundant isotope of carbon, in that it has an extra neutron in its nucleus, but otherwise its chemical properties are the same. It accounts for just 1% of all carbon atoms, with carbon-12 accounting for the other 99% (there are also some other very low abundance isotopes).
