The nitrogen atom, which began with seven protons and seven neutrons, is left with only six protons and eight neutrons.As the number of protons decides the chemical nature of an atom, the atom now behaves like a carbon atom.

The ions produced are forced into a magnetic field where the different mass of the carbon isotopes causes a different deflection, allowing the quantity of each isotope to be measured.

This method is claimed to be more accurate than the older and slower method of counting the number of radioactive decay emissions from a quite large sample.

The radioactive carbon has six protons and eight neutrons in its nucleus, giving it a total atomic mass of 14.

This atom is not stable, and will break down, releasing nuclear energy in the process.

The carbon dioxide is absorbed by plants, and the plants are eaten by animals, thus contaminating every living thing on earth with radioactive carbon. As time passes, the C14 in its tissues is converted back into nitrogen.

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.

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.

However, because it has too many neutrons for the number of protons it contains, it is not a stable atom.

Every 5,730 years, approximately half of this radioactive carbon spontaneously converts itself back into nitrogen by emitting an electron from a neutron.

As you might guess, radioactive carbon (C) is quite rare.
