Because it reacts identically to C-12 and C-13, C-14 becomes attached to complex organic molecules through photosynthesis in plants and becomes part of their molecular makeup.Animals eating those plants in turn absorb Carbon-14 as well as the stable isotopes.As the number of protons decides the chemical nature of an atom, the atom now behaves like a carbon atom.

This limit is currently accepted by nearly all radiocarbon dating practitioners.

This is actually a mini-simulator, in that it processes a different sample each time and generates different dates.

The normal carbon atom has six protons and six neutrons in its nucleus, giving a total atomic mass of 12.

Radiocarbon dating is frequently used to date ancient human settlements or tools. It is a stable atom that will not change its atomic mass under normal circumstances.

BASIS OF RADIOCARBON DATING Radiocarbon dating compares the amount of normal carbon with the amount of radioactive carbon in a sample.If we know what the original ratios of C14 to C12 were in the organism when it died, and if we know that the sample has not been contaminated by contact with other carbon since its death, we should be able to calculate when it died by its C14 to C12 ratio.
