Which isotope is found in living things or radiocarbon dating?
This is the isotope carbon-14.
What is the isotope of carbon that is used for dating things in archaeology?
carbon 14
What is the source of the carbon that is used in radiocarbon dating in living things?
The radioactive isotope carbon-14 is natural.
The isotope often used to determine the age of once living things?
Carbon-14, a naturally occurring isotope of carbon in the atmosphere. After death, a living thing does not take in nutrients from the atmosphere and thus do not take in Carbon-14, thus the carbon-14 in their body start to diminish at a predictable rate. By measuring the amount of carbon-14 left in a dead matter, the time since death can be determined. Note that this method is only accurate up to 60,000 years old.
Can carbon dating be used on a stone to determine it's age?
It is not possible to carbon date rocks. Carbon 14 dating is based on the absorption of atmospheric carbon by livingthings. When the thing dies it no longer takes in carbon from the atmosphere through processes such as eating or respiration and levels of C14 in the body deplete due to the natural process of radioactive decay. By seeing how much C14 remains it is possible to see how long it has been since that animal died.However there are a range of other dating methods which can be used.

What dating process works only on once living things?
Radiocarbon dating is a process that works only on once living things. It relies on measuring the amount of carbon-14 present in organic materials to determine their age, as carbon-14 undergoes radioactive decay after an organism dies. This dating method is commonly used in archeology and paleontology to determine the age of fossils and artifacts.
Are there any limits to carbon dating?
Yes:it cannot date things older than ~40,000 years as the carbon-14 isotope has decayed to practically undetectable levels after that much timeas levels of the carbon-14 isotope in the atmosphere vary slightly over time (it is produced by the flux of cosmic rays hitting earth, which varies as the solar system orbits the galaxy, etc.) the dating method must be recalibrated using tree ring count reference samples to keep it accurate over long periods of timeof course it can only be used to date things that were once living, and thus in equilibrium with atmospheric carbon isotope ratios at the time of deathoceanic carbon isotope ratios are different from atmospheric carbon isotope ratios, so this must be accounted for in dating sea creature fossils
What is carbon 13?
Carbon-13 is a stable isotope of carbon, meaning it has the same number of protons but a different number of neutrons compared to the more common isotope, carbon-12. It makes up about 1.1% of naturally occurring carbon and is often used in scientific research, such as in nuclear magnetic resonance (NMR) spectroscopy to study the structure of molecules.
What is the source of the carbon that is used in radiocarbon dating in living things?
The radioactive isotope carbon-14 is natural.
Which isotope is found in all living things?
Carbon 14 is one.
What is the isotope found in all living things?

Why carbon dating works?
It works, among other things, because:* Like any radioactive isotope, C-14 (the radioactive carbon used for this) decays at a constant (and known) rate. * C-14 is replenished in the atmosphere. * Carbon is absorbed by living beings; and when these die, no more carbon is ingested by them.
