How long is a half-life for carbon-14_____ 8 if only 25% of the carbon-14 remains, how old half-life worksheet author: michael richez created date. Carbon dating is based upon the decay of 14 c, a radioactive isotope of carbon with a relatively long half-life (5700 years) while 12 c is the most abundant carbon isotope, there is a close to constant ratio of 12 c to 14 c in the environment, and hence in the molecules, cells, and tissues of living organisms.

(also referred to as carbon dating or carbon-14 dating) the half-life of a (1984) radiocarbon dating: some problems and potential.

Carbon-14 has a half-life of 5730 years you are presented with a document which purports to contain the recollections of a mycenaean soldier during the trojan war the city of troy was finally destroyed in about 1250 bc, or about 3250 years ago carbon-dating evaluates the ratio of radioactive carbon-14 to stable carbon-12. Carbon dating lesson plans and worksheets from half life problems of carbon 14 remaining in a plant in this real-life task centered on carbon dating. Many people believe carbon-14 dating the half-life of an atom is the the results of the carbon-14 dating demonstrated serious problems for. Carbon 14 dating calculator to find the percent of carbon 14 remaining after a given number of years, type in the number of years and click on calculate.

In the case of radiocarbon dating, the half-life of carbon 14 is 5,730 years this half life is a relatively small number, which means that carbon 14 dating is not particularly helpful for very recent deaths and deaths more than 50,000 years ago.

Scientists look at half-life decay rates of radioactive isotopes to estimate when a particular atom might decay a useful application of half-lives is radioactive dating.
