Many people assume that rocks are dated at “millions of years” based on radiocarbon (carbon-14) dating. The most well-known of all the radiometric dating methods is radiocarbon dating. Carbon-14 can yield dates of only “thousands of years” before it all breaks down.Research has been ongoing since the 1960s to determine what the proportion of in the atmosphere has been over the past fifty thousand years.The resulting data, in the form of a calibration curve, is now used to convert a given measurement of radiocarbon in a sample into an estimate of the sample's calendar age.

However, a correction can be made on the basis of carbon 14 readings on items whose age is known from archeological records.Protons and neutrons make up the center (nucleus) of the atom, and electrons form shells around the nucleus.The number of protons in the nucleus of an atom determines the element.Creation Position Many living things are not in equilibrium for C-14 exchange; the shells of living mollusks show radiocarbon ages of up to 2300 years.

The rate of carbon 14 radioactive decay may have been different in the past.Carbon 14 is formed from carbon 12 in the atmosphere by the action of cosmic rays.
