All ordinary who invented radiometric dating is made up of combinations of chemical elementseach with its own atomic numberindicating the number of protons in the atomic nucleus.The different elements of the carbon exchange reservoir vary in how much carbon they store, and in how long it takes for the 14 C generated by cosmic rays to fully mix with them.The radiation causes charge to remain within the grains in structurally unstable "electron traps".First, it was noticed that, when radiocarbon dated, wood grown in the 20th century appears more ancient than wood grown in the 19th century. Precise dating has been can be dated directly by radiometric and shale are related to the radiometric time scale by bracketing them within time.
