Assumptions does carbon 14 dating rely
This tendency to decay, called radioactivity, is what gives radiocarbon the name radiocarbon.
The atmosphere contains many stable carbon atoms and relatively few radiocarbon atoms.
Perhaps no concept in science is as misunderstood as "carbon dating." Almost everyone thinks carbon dating speaks of millions or billions of years.
Unlike carbon-12 which is stable, carbon-14 decays over time and must constantly be replaced.Part of the result of these collisions is the production of radiocarbon (C, pronounced "c fourteen"), carbon atoms which are chemically the same as stable carbon, but have two extra neutrons.Radiocarbon is not stable; over time radiocarbon atoms decay into nitrogen atoms.The changing ratio of C-12 to C-14 indicates the length of time since the tree stopped absorbing carbon, i.e., the time of its death.Obviously, if half the C-14 decays in 5,730 years, and half more decays in another 5,730 years, by ten half-lives (57,300 years) there would be essentially no C-14 left.
