In chemistry I was taught one carbon atom can exist in at least 12 separate living bodies before it's no longer stable.
Hon I think you maybe misunderstood your chem class.
Carbon is carbon is carbon and doesn't know or care if it's in a living body.
Carbon-14 has a half life of 5700 years. This means that through random decay, the approximate rate of decay is one half of a given amount every 5700 years, this of course breaks down when you reach the single-digit quantities of atoms.
Now, this has nothing to do with the stability of an atom of regular-ass carbon-12, your common garden variety carbon, which is extremely stable and would require outside influence to decay into another isotope.
Ahhh I misremembered. It was this "The average carbon atom in our bodies has been used by twenty other organisms before we get to it and will be used by other organisms after we die."
It's been six years since that class.
that doesn't make any sense. Carbon doesn't get less stable by being used in bodies.
Carbon 14 exists, but that decays regardless if it's in a body or not. At has quite a long half life
Yea, I misremembered it. It was in my book from a while back. Here we go:
At least is a heavy lifting qualifier in this case.
What does that mean?
After you die, the carbon atoms that made you might go on to make another living thing.
