Conduct activity on relative and absolute dating two ways to skin a cat relative dating of fossils is a system in which a fossil is given an age designation in terms of epoch, period, or era which can be compared to other geologic units of time as older or younger, but without the burden of assigning a specific number. Carbon-14, the radioactive isotope of carbon used in carbon dating has a half-life of 5730 years, so it decays too fast it can only be used to date fossils younger than about 75,000 years potassium-40 on the other hand has a half like of 125 billion years and is common in rocks and minerals. Carbon dating works by comparing the amount of carbon-14 in a sample to the amount of carbon-12 because organisms stop taking in carbon-14 at death, the age of the material can be precisely determined by this ratio of carbon isotopes human remains, fossils and organic materials from archaeological sites are all dated using carbon-14.

Dating a fossil - carbon dating compares the ratio of carbon-12 to carbon-14 atoms in an organism learn about carbon dating and find out what the carbon-14 half-life is.
Radiocarbon dating all carbon atoms have 6 protons in the nucleus, but the nucleus may also contain 6, 7, or 8 neutrons carbon-12 carbon with 6 protons and 6 neutrons is called carbon-12 (12c) this is a stable nucleus 99% of all natural carbon is 12c carbon-13. So carbon by definition has six protons, but the typical isotope, the most common isotope of carbon is carbon-12 so carbon-12 is the most common so most of the carbon in your body is carbon-12.
