Question

An application of the half life of which isotope can be used to determine age of organic material?

carbon-14
carbon-12
carbon-13
carbon-10

Answer 1

The answer is carbon-14

Answer 2

Answer: option A C-14

Explanation:

Since C-14: isotope is radioactive and had maximum half-life.

Hence it is used to determine the age of organic materials by the process called dating or C-14 dating.

C-13 is used in C-NMR spectrometry and C-12 is inactive.

So A is correct.
