For example, if you start off with 1000 radioactive nuclei with a half-life of 10 days, you would have 500 left after 10 days; you would have 250 left after 20 days (2 half-lives); and so on. The radiocarbon age of a certain sample of unknown age can be determined by measuring its carbon 14 content and comparing the result to the carbon 14 activity in modern and background samples. The half-life is the time required for half of the original sample of radioactive nuclei to decay. But carbon-14 dating won't work on dinosaur bones. If an organism had 100 grams of carbon-14 when it died, after 5730 years, how many grams of carbon-14 would it have? Carbon is extremely important for the existence of almost all the organic and inorganic things present on the earth. Look at this diagram here describing this. All carbon atoms have 6 protons in the nucleus, but the nucleus may also contain 6, 7, or 8 neutrons. Radiocarbon dating uses the naturally occurring isotope Carbon-14 to approximate the age of organic materials. Ever wondered how scientists know the age of old bones in an ancient site or how old a scrap of linen is? This radioactive carbon 14 slowly decays back into normal, stable nitrogen. Measuring the amount of radioactive carbon-14 remaining makes it possible to work out how old the artifact is, whether it's a fossilized skeleton or a magnificent piece of artwork. I certainly love this website. Carbon has two stable, nonradioactive isotopes: carbon-12 (12C), and carbon-13 (13C). There are three carbon isotopes that occur as part of the Earth's natural processes; these are carbon-12, carbon-13 and carbon-14.
