14c carbon dating
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.
But in actual practice, we know neither the original ratios nor if the specimen has been contaminated and are forced to make what we hope are reasonable assumptions.
As the number of protons decides the chemical nature of an atom, the atom now behaves like a carbon atom.
However, because it has too many neutrons for the number of protons it contains, it is not a stable atom.

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.Background: Radiocarbon dating of materials is a radiometric dating technique that uses the decay of carbon-14 (14C) to estimate the age of organic materials, such as paper and parchment.The method has been used to date the substrate of a range of significant items, however it should be noted that carbon dating can only date the material itself, the paper or parchment, not media used to add content to the parchment or paper substrate.
