They are both forms allotropes of carbon. Most carbon atoms are 12 times heavier than hydrogen 12 Cabout one in is 13 times heavier 13 Cand one in a trillion 10 12 is 14 times heavier 14 C. Of these different types isotopes of carbon, 14 C is called radiocarbon, because it is radioactive—it breaks down over time. Some try to measure age by how much 14 C has decayed.
The use of carbon, also known as radiocarbon, to date organic materials has been an important method in both archaeology and geology.
