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.
N14
The order of half-life from shortest to longest is: P32 (phosphorus-32), S35 (sulfur-35), C14 (carbon-14), and H3 (tritium).
with C14 atom
No. Volcanic ash is composed largely of silica and metal oxides, with little or no carbon. The materal that the ash originates from has been inside the earth for millions, if not billions of years, so if there were any C14 in it to begin with, it would have decayed into immeasureably small quantities.
Total of 29 atoms (14 carbon, 12 hydrogen and 3 oxygens).
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.

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.
