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.
However, a team of empirical science investigators, using routine carbon-14 radiometric dating methodology, rejected that historical timeframe, arguing instead for dating the skeletons a century or so older based upon residual carbon-14 found inside the bones.
Why would radiocarbon calculations indicate the buried warriors died during the 600s or 700s, a century or more before Derbyshire was overwhelmed by hordes of Vikings?
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.
Every 5,730 years, approximately half of this radioactive carbon spontaneously converts itself back into nitrogen by emitting an electron from a neutron.
