Which is radioactive, C-12 or C-14?
Whether C-12 is radioactive or C-14.
Explanation of Solution
Introduction:
The radioactive elements that are chemically identical but differ in the number of neutrons in the nucleus of atom is called radioactive isotope.
The radioactivity arises due to instability in the nucleus of the atom. The instability of atom depends on the nucleus of the atom. The heavier is the nucleus of the atom more is the instability in nucleus, so the radioactivity of atom.
The nucleus of C-14 atom is heavy compared to C-12. So. C-14 is the radioactive isotope of the carbon.
Conclusion:
Thus, C-14 is the radioactive isotope of the carbon.
