Describe the process of carbon dating
The nitrogen atom, which began with seven protons and seven neutrons, is left with only six protons and eight neutrons.As the number of protons decides the chemical nature of an atom, the atom now behaves like a carbon atom.As you might guess, radioactive carbon (C) is quite rare.Only one out of every trillion carbon atoms is C14. The C14 created in the upper atmosphere reacts with oxygen to become carbon dioxide.
This atom is not stable, and will break down, releasing nuclear energy in the process....[Some authors have said] they were "not aware of a single significant disagreement" on any sample that had been dated at different labs.Such enthusiasts continue to claim, incredible though it may seem, that "no gross discrepancies are apparent".However, because it has too many neutrons for the number of protons it contains, it is not a stable atom.Every 5,730 years, approximately half of this radioactive carbon spontaneously converts itself back into nitrogen by emitting an electron from a neutron.
