- 6 Carbon-14 (C) dating is a method for finding the age of an organic artifact from the quantity of 14C it contains. Carbon-14, an unstable isotope of carbon, follows a well-known sequence of decay processes. The decay constants of these processes have been well established, allowing researchers to determine the age of an artifact knowing both the original amount of 14C and the current amount. In the lab, it is relatively easy to measure the activity of a sample and to estimate the mass of carbon in the sample. From these measurements, it is possible to find the age of the sample.arrow_forward- 3. | Consider the nuclear reaction He + Li → B + on. Is energy absorbed or liberated?
