This atom is not stable, and will break down, releasing nuclear energy in the process.Radioactive carbon (Carbon 14) is formed in the upper atmosphere as a byproduct of cosmic radiation.The proton takes an electron with it and becomes an atom of hydrogen.The nitrogen atom, which began with seven protons and seven neutrons, is left with only six protons and eight neutrons.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.

PROBLEMS WITH RADIOCARBON DATING During the last 30 years, a new method of determining C14/C12 ratios has been developed.

But an error of 2,000 years is of great importance,” says Riede.

Before they started on the research project, the archaeologists were fully aware that dating of fish is subject to a large margin of error.

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.

Carbon-14 dating of potsherd from ancient people’s clay vessels is commonly used to determine the age of a Stone Age settlement.
