A:
- Unstable nuclei will decay into stable ones. This process is called radioactive decay. This process can be used to calculate the age of organic compounds.
- Radiocarbon dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon.
- Radioactive decay is exponential in nature and can be written as,
Here N0 is the original number of radioactive nuclei present, t is the time, and t1/2 is the half-life of the radioactive sample. This is known as the exponential law of radioactive decay.
