It cannot be used to date rocks, both because of its short half life (about 5,000 years), and because it can only be used to date the remains of living things (such as bones, or wood). No, carbon dating is the amount of an isotope of carbon in a fossil, Carbon 14.The amount of Carbon 14 is predictable over a time line, and the area of the time line the amount of C14 that occurs in that fossil will be a fairly accurate indication of it's approzimate age.Carbon dating is a method of telling approximately how old an ancient object is. Carbon atoms are contained in every part of every cell of allliving things on Earth.Most carbon atoms (98.89%) are calledcarbon-12 because they have 6 neutrons and 6 protons in theirnuclei.A lot of lab-created elements break down secondsafter they're created, which is why there aren't a million elementsin the table yet. Carbon-dating can not be used to prove the age of the earth, so it can not be used either to prove a "young earth" nor to support the scientific age of the earth.Carbon-dating is useful for archaeology, where it can date evidence of human artefacts up to fifty thousand years old.All life forms have a set ratio of carbon to other substances in their bodies and by seeing how much this carbon has depleted they can see how many years have gone by since death (the...

because the number of protons has changed, so has the element.After death, this carbon 14 starts to leave the body in question.Hense, if a sycamore tree is created with 40,000 carbon 14 atoms and loose 48 a year, after a... Carbon dating tells how long ago something died (more specifically, when it stopped absorbing carbon).This atomic event is random andcannot be predicted, but by applying...Because its nucleus is in an unstable excited state.
