C-12 is stable, meaning it does not decay into other elements over time. It is formed when cosmic radiation strikes N-14 (Nitrogen), converting it into C-14, and it decays back into N-14, with a half-life of 5730 years, meaning that for any sample of C-14, half of it will decay back into N-14 every 5730 years.Carbon-14 is used to date dead plants and animals, because plants and animals incorporate C-14 into their bodies by eating, drinking, and breathing in an environment containing C-14.
Scientists now know that most elements come in more than one version. When the dry periods ended and the water level rose, the trees drowned, marking the end of the droughts.
Since then, the remains of those trees have been well preserved by the arid climate. To determine how long ago these droughts occurred, Scott is using carbon-14 to date the trees.
Unlike the other natural isotopes of carbon, carbon-14 is unstable. One of its neutrons turns into a proton and spits out an electron.
Now, with seven protons instead of six, it's turned into nitrogen. And scientists know exactly how long it will take for half of any amount of carbon-14 to decay away.
Professor Willard Libby produced the first radiocarbon dates in 1949 and was later awarded the Nobel Prize for his efforts.
