Maybe some earth day quickly, we’ll know what nature is worth
The carbon-14 atoms are always decaying, but they are being replaced by new carbon-14 atoms at a continuing rate. At this second, your physique has a sure percentage of carbon-14 atoms in it, and all residing vegetation and animals have the same proportion. Carbon courting, additionally known as radiocarbon courting, was found by Willard Frank Libby in the 1940s. Carbon exists in three types, or isotopes, carbon-12 (12C), carbon-13 (13C), and carbon-14 (14C).
