After radiocarbon forms, the nuclei of the carbon atoms are unstable, so over time they progressively decay back to nuclei of stable nitrogen Science What Is Science?
The standard way of expressing the decay rate is called the half-life. Human life is sacred, from conception until the day we die. This carbon dioxide, now radioactive with carbon, is otherwise chemically indistinguishable from the normal carbon dioxide in the atmosphere, which is slightly lighter because it contains normal carbon The difference in the number of sand grains represents the number of carbon atoms that have decayed back to nitrogen since the mammoth died.
