Carbon dating chemistry

Hence, the ages are specified as 3400 BP (3400 years BP). The flaw in this method is that it assumes that the carbon-14/carbon-12 ratio has been the same till 1950, which is not the case in reality.

The impact of this technique on the world of science, led to Libby being awarded the Nobel prize in chemistry, in 1960.

This dating method is based on comparison of ratios of two carbon isotopes, which are C-12 and C-14. Isotopes are elements with the same atomic number, but different atomic mass numbers. By comparing the amount of radioactive carbon present now, with the amount at the beginning, an age estimate can be made, based on laws of radioactive decay.

Although this can be a challenging idea to comprehend at first, there is indeed …

This may lead to an inaccurate determination of age. This dating technique is inaccurate at times but its error levels are very low and certainly not inaccurate enough to be called wrong.

Accuracy of this dating technique is not perfect, but it has given remarkably precise results, when tested to calculate age of artifacts, whose age was known, by other methods.

Why was carbon chosen for the dating method, out of all the radioactive elements?
