It is called an Isotope.... C12, C13, C14 is a classical example
The main ones are using c14. Radiocarbon dating gives acurate dating of historic and prehistoric organic materials. Also, c14 is used to "tag" carbon compounds to track how different sources of carbon are used in molecular biology/biochemistry. Additionally, c3 and c4 plants (this difference is in the regulation of photosynthesis) take in carbon isotopes at different rates. A c4 plant (like corn) will use c13 as readily as c12. However, c3 plants will not use c13 as readily as c12. This means that the ratio of c12 to c13 is different in c3 plants then in c4 plants. More importantly, the ratios are kept through tropic levels: when an animal uses carbon from a c4 plant, the ratio of c12 to c13 will be the same as in the plant. The use: we (humans in general) can analyze the ratio of c12 to c13 in animals, showing if they consume mostly c3 or c4 plants. This means that we can track carbon through a food chain or see if an historic tribe consumed more land based food (more likely c4) or sea food (completely c3). The studies that show that people from the US are 90% corn? Corn is the most common c4 food/carbon source today, and this type of study finds that people in the US have a c12 to c13 ratio that corresponds to 90% of our food to be derived from c4 plants.
In Carbon-12, the most abundant form of Carbon, there are 6 Neutrons, 6 Protons and 6 Electrons. In Carbon-14, the radioactive isotope of Carbon used in Carbon Dating, has 6 Protons, 8 Neutrons and 6 Electrons.

Carbon is available in three isotopes, C12, C13 and C14. C12 is the most common.

carbon exists as 3 naturally isotopes c12 c13 c14 as he number of neutrons increase in the isotope the nuclear charge
11 Carbon has atomic(proton) number 6. i.e it has 6 protons. There are three naturally occurring isotopes for carbon. They are C12 c13 and c14. among them c14 is radioactive. c12 has 6 protons and 6 neutrons. c13 has 6 protons and 7 neutrons. c14 has 6 protons and 8 neutrons. Similarly, c17 has 6 protons and 11 neutrons.

C12 and C14 are isotopes of the Element Carbon. C12 is the most abundant of all which is 99% of all the Carbon on earth while C14 is only 0.0000000001% (trace amount). C12 has a Atomic Number of 12. It has 6 Protons and 6 Neutrons. C14 has a Atomic Number of 14. It has 6 Protons and 8 Neutrons. C14 is radioactive in nature. It is used for carbon dating.
In Carbon-12, the most abundant form of Carbon, there are 6 Neutrons, 6 Protons and 6 Electrons. In Carbon-14, the radioactive isotope of Carbon used in Carbon Dating, has 6 Protons, 8 Neutrons and 6 Electrons.
Isotopes have the same numbers of protons but different numbers of neutrons. One of the most common examples is carbon: C12 is the standard carbon atom, but C13 and C14, although still carbon atoms, have one or two extra neutrons.

It is because living organisms absorb C14 from their environment. After death, they are no longer capable of absorbing any more C14. So, at the time of death, the C14 : C12 ratio is fixed. C14 undergoes radioactive decay (into C12) so the C14 : C12 ratio declines and that can be used as a measure of the time since death.
