The radioactive carbon has six protons and eight neutrons in its nucleus, giving it a total atomic mass of 14.This atom is not stable, and will break down, releasing nuclear energy in the process.Usually a proton is knocked out of the nitrogen atom's nucleus and is replaced with the neutron.The proton takes an electron with it and becomes an atom of hydrogen.

It follows that the older a date is, even within this 'limit', the greater are the doubts about the date's accuracy.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.When they strike ordinary atoms in the upper atmosphere, the cosmic rays smash them apart. Some of these neutrons then collide with nitrogen atoms.This collision is less destructive than the initial collision that produced them.
