Ninety-nine percent of these also contain six neutrons.The 6 proton 6 neutron atoms are said to have a mass of 12 and are referred to as "carbon-12." The nuclei of the remaining one percent of carbon atoms contain not six but either seven or eight neutrons in addition to the standard six protons.

The article is in straightforward language and the non-technical reader could profitably work through it.

, we find that this ration is the same if we sample a leaf from a tree, or a part of your body.

Carbon-14 has a half-life of 5,730 ± 40 years— during the succeeding 5,730 years.

Because carbon-14 decays at this constant rate, an estimate of the date at which an organism died can be made by measuring the amount of its residual radiocarbon.

Atoms of the same element that have different numbers of neutrons are called isotopes. Most carbon on Earth exists as the very stable isotope carbon-12, with a very small amount as carbon-13.
