neutral atom would have the same number of protons and electrons, so a neutral atom of carbon-12 or carbon-14 would have 6 electrons.

Although neutrons do not carry an electrical charge, they have a mass comparable to that of protons, so different isotopes have different atomic weight. Because of the different number of neutrons, carbon-12 and carbon-14 differ with respect to radioactivity. Carbon-14, on the other hand, undergoes radioactive decay:e (half-life is 5720 years)The other common isotope of carbon is carbon-13. "What Is the Difference Between Carbon-12 and Carbon-14?

Atoms of the same element that have different numbers of neutrons are called isotopes. Most carbon on Earth exists as the very stable isotope carbon-12, with a very small amount as carbon-13.The difference between carbon-12 and carbon-14 is the number of neutrons in each atom.The number given after the atom name (carbon) indicates the number of protons plus neutrons in an atom or ion.When an organism dies it ceases to replenish carbon in its tissues and the decay of carbon 14 to nitrogen 14 changes the ratio of carbon 12 to carbon 14.

Experts can compare the ratio of carbon 12 to carbon 14 in dead material to the ratio when the organism was alive to estimate the date of its death.Carbon-13 has 6 protons, just like other carbon isotopes, but it has 7 neutrons. Although 15 isotopes of carbon are known, the natural form of the element consists of a mixture of only three of them: carbon-12, carbon-13, and carbon-14. Measuring the difference in the radio between carbon-12 and carbon-14 is useful for dating the age of organic matter since a living organism is exchanging carbon and maintaining a certain ratio of isotopes.
