The Relevence of Carbon-14 - 653 Words

A human skeleton is discovered at a new construction site outside a small town in Nebraska. The remains could be from someone who died within the past 100 years or the past 1000 years or even longer. An archeologist from a local university is called in to examine the remains. He finds evidence that the skeleton may indeed be very old. To determine its age, he uses radiometric dating. Radiometric dating is based on analyzing the amount of carbon-14 in an ancient example of once-living substantial, related to what is found in a current sample of active material. The important material on which it is established is that carbon-14 has always been constructed at the same level in the greater atmosphere for all history. An element is radioactive if its atomic nuclei are unstable. The nucleus holds neutrons and protons; the electromagnetic force separates the protons because they have an equivalent charge, but the strong nuclear force pulls the protons and neutrons closer together. A nucleus is only unchanging if it has an even balance of protons and neutrons, or also doesnt have any extra energy. Radiocarbon dating only works on things that were once alive and are now dead. The level of carbon 14 in an artifact reduces by 50% every 5730 years from the moment that the raw material from which the artifact is made no longer is exchanging carbon with he atmosphere, in most cases this is the point of death of the animal or plant. Carbon-14 is produced naturally in the upper
