Question

How can carbon-14 be converted to carbon-12?

Answer 1

It can't.

Explanation:

Carbon 14 (or `""^14C`) is an unstable isotope of carbon with 8 neutrons instead of the typical 6.

When `""^14C` decays, it does so by beta decay, releasing a beta particle as one neutron becomes a proton. The product of the decay of `""^14C` is nitrogen, `""^14N`.
