Chapter 39, Problem 19A

Why is more C-14 found m new bones than in ancient bones of the same mass?

To determine

The reason for finding of C-14 in the new bones than the ancient bones of same mass.

Explanation of Solution

Introduction:

The radioactive process in which the initial amount of the radioactive material reduces is called the radioactive process. The radioactive process occurs due to ejection of radioactive particles to stabilize the nucleus of the atom.

The amount of C-14 in ancient bones reduces due to the radioactive decay and the decayed amount of the carbon in C-14 is not replaced by other carbon atoms.

The amount of C-14 in bones reduces and replaced by the other molecules of the carbon. So, the amount of C-14 is more in the new bones than the ancient bones of same mass.

Conclusion:

Thus, the amount of C-14 is more in the new bones than the ancient bones of same mass because the decayed C-14 molecules are replaced by new C-14 in new bones.
