Carbon-14 (C-14) is a rare isotope of carbon produced in the upper atmosphere when a cosmic ray strikes an atom of nitrogen. Carbon-14 is radioactive undergoing beta decay to nitrogen-14 with a halflife of 5570 years. Because it is produced at a near constant rate and living organisms maintain the same percentage of it as is present in the atmosphere while they are alive, but after an organism dies it can no longer equalize the amount of the carbon-14 in its tissues, this isotope's decay can be used as a "clock" to measure the time since the organism died.

∙ 13y agoC14 is a type of atom that is used for radioactive dating to date rocks and fossils. C-14 has a half-life 5,740 years. The half-life is short because C-14 is not a stable atom.

List a range of items that can be dated by isotope carbon 14?
It is not that simple. Carbon 14 (C14) is created in the upper atmosphere by the action of cosmic rays on Nitrogen atoms. There is not much of it, C14 occurs in trace amounts, only making up as much as 1 part per trillion (0.0000000001%) of the carbon on the Earth. This amount of C14 is in balance, the amount created in the upper atmosphere balances the amount lost by the natural radioactive decay of the isotope. All living things on earth, are made of chemicals that include carbon and, while living, the amount of C14 in them is in balance with the amount of C14 in the atmosphere. However when a living thing dies it no longer mixes the carbon in its body with that of the atmosphere and thus the amount of C14 it contains begins to reduce to levels below that found in the atmosphere because the C14 decays radioactively. Thus items to be dated using C14 must contain carbon (wood, charcoal, hair and bones are good) and must have remained undisturbed since the organisms death. Also C14 decays rather quickly and is therefore only good for dating items that are less than about 60,000 years old.

The half-life of C14 is 5730 years. What fraction of the original C14 would you expect to be present in a fossil that is 28650 years old?
There would be 1/32 left.
What half-life of C14 is 5730 years. What fraction of the original C14 would you expect to be present in a fossil that is 28650 years old?
1/32 of the original amount.
What is the difference between c 12 and c 14?
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.
What type of cell reference is C14?
It is a relative cell reference.
What is the daughter product of the nuclear decay equation of C14?
N14
What actors and actresses appeared in C14 - 2013?
The cast of C14 - 2013 includes: Dustin Bacon as Random Guy Craig Bouwens as Zombie 2 David Scott Diaz as David
What fraction of the original c14 would you expect to be present in a fossil that is twenty eight thousand six hundred and fifty years old?
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.
How many isotopes dose c have?
3 - c12, c13 and c14
