are thus isotopes of carbon-12. Where, t1/2 for 146C is 5760 years.

Thus in 11,520 years the 146C concentration is reduced to one fourth of its initial concentration. Answer, find more words! This radioactive 14CO2 is taken up by plants during photosynthesis. Ninety-nine percent of these also contain six neutrons.

A hydrocarbon found in beach sediments, for example, might derive from an oil spill or from waxes produced by plants. Carbon is one of the chemical elements. He was awarded Nobel Prize for this work.

When isotopes are to be designated specifically, the chemical symbol is expanded to identify the mass (for example, 13C). Isotopes participate in the same chemical reactions but often at differing rates. If 14C is present at atmospheric levels, the molecule must derive from a recent plant product. In the upper atmosphere, nitrogen (147N) is bombarded by cosmic ray to produce 146C : (146C is a radioactive isotope of carbon). Radiocarbon dating or in general radioisotopic dating method is used for estimating the age of old archaeological samples. This technique was developed by Williard Libby.
