Its use in Nature by Nature is not known. The atom decays with a half life of something like 14,000 years and is present in all carbon in the earth at a certain percentage. Thus a gram of any organic substance (an organic substance is one that possess carbon and oxygen; carbon is present in food (polysaccharides, fats, sugars, proteins; and in all tissues of the body and it is present at the % that it is present on earth thruout life. When an animal or plant dies, it stops taking in C14 or any carbon when it dies. As time goes on, the % of Carbon in the dead plant of animal that is C14 decreases as C14 decays by ejection of an electron (beta decay). As this happens, the 5 of total carbon that is radioactive decreases continuously, Scientists can determine how long ago the animal died by determining how much C14 radioactivity is in a gram of that organisms carbon. If the organism died 14,000 years ago, the % would be about half of that in the earths environment (then and now, that doesn't change). Aside from its use for that calculation, C14 has no known "use" but is a product of natural radioactive decay and plays a central role in universal homeostasis.

C14 - 2013 was released on: USA: 30 October 2013 (limited)
The simplest and best way is: =SUM(C1:C14)
Yes.
1/32 of the original amount.
There would be 1/32 left.
C12 and C14 are isotopes of the Element Carbon. C12 is the most abundant of all which is 99% of all the Carbon on earth while C14 is only 0.0000000001% (trace amount). C12 has a Atomic Number of 12. It has 6 Protons and 6 Neutrons. C14 has a Atomic Number of 14. It has 6 Protons and 8 Neutrons. C14 is radioactive in nature. It is used for carbon dating.
It is a relative cell reference.
N14
The cast of C14 - 2013 includes: Dustin Bacon as Random Guy Craig Bouwens as Zombie 2 David Scott Diaz as David
The half-life of C14 is 5730 years so the given period is 5 half-lives. You should, therefore, expect approx 2-5 = 0.03125 of the original C14 to remain.

Scientists explain the presence of C14 in dinosaur bones as contamination from modern sources, such as bacteria or groundwater, rather than indicating a recent age for the bones.
