Which of the following isotopes of carbon is/are used in carbon dating?
Correct answer: C. 6C14
- A. 6C12
- B. 6C13
- C. 6C14
- D. 6C12 , 6C14
Explanation
Carbon-14 is a radioactive isotope of carbon that is used in carbon dating, also known as radiocarbon dating. The method works by measuring the amount of carbon-14 in a sample of organic material, such as wood, bone, or cloth, and comparing it to the initial amount of carbon-14 in the atmosphere.

About Radioactive Decay
Radioactive decay is the spontaneous transformation of unstable nuclei, described by decay constant, activity, half life and the exponential decay law. Work includes alpha, beta and gamma emissions, decay equations and remaining nuclei, with half life distinguished from the time required for complete decay.
