Q. Which of the following carbon isotopes is/are used in Carbon Dating?- C12
- C13
- C14
Select the correct option from the codes given below:
Answer:
Only 1 & 3
Notes: Carbon dating specifically utilizes C14, a radioactive isotope with a half-life of about 5,730 years. C12 and C13 are stable isotopes and do not decay over time. In carbon dating, the ratio of C14 to C12 (and sometimes C13 for correction) is measured to estimate the sample's age. Hence, only C14 is directly used.
