Carbon-14. Carbon has a twin brother that only a few know about. Our planet is constantly pelted with high-energy cosmic rays hurled by the sun. These rays, which teem with neutrons, react with the nitrogen in our atmosphere to produce carbon-14 or C-14 atoms, an isotope of the carbon-12 or C-12 atom.
Photosynthetic algae (marine phytoplankton) appeared to be more active in the near-surface waters overlying the seafloor methane seeps, a phenomenon that would explain why so much carbon dioxide was.
In Carbon-14 decay, the unstable Carbon-14 atom (C-14) is referred to as the parent and the Nitrogen-14 atom is known as the daughter. In some radioactive decay processes, such as for Uranium-238, once the U-238 isotope decays, there is a long series of other unstable isotopes before you finally come to a stable one that does not decay (Lead-206).
