Radioactive carbon dating definition

Isotopes participate in the same chemical reactions but often at differing rates.

When isotopes are to be designated specifically, the chemical symbol is expanded to identify the mass (for example, C is not stable.

Thus, as living things take in carbon, they inevitably will take up a small amount of radioactive carbon into their bodies.

One-star words are frequent, two-star words are more frequent, and three-star words are the most frequent.

The amount of carbon-14 in the air has stayed the same for thousands of years.

There is a small amount of radioactive carbon-14 in all living organisms because it enters the food chain.

The carbon in their bodies at the time of their death will remain in their bodies until they decompose, or if they become fossilized, then forever. This allows scientists to look at the amount of decay in a fossil’s radioactive carbon and determine a relative date.

Radiocarbon dating is only effective for objects and fossils that are less than 50,000 years old.
