"You humans"? I was unaware that any other species could type, let alone spell so well.
14C is naturally produced from 14N by solar irradiation and remains essentially constant in living organisms.
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.
C12, C13, and C14 are isotopes of carbon, differing in the number of neutrons in their atomic nuclei. C12, the most abundant isotope, has 6 neutrons, while C13 has 7 neutrons, and C14, a radioactive isotope, has 8 neutrons. These isotopes are significant in various fields, including geology, archaeology (carbon dating with C14), and environmental science, as they help in understanding carbon cycling and dating ancient organic materials.
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.
