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. Radiocarbon . The equation is most conveniently expressed in terms of the measured quantity N (t) rather than the constant initial value No. Although we now recognize lots of problems with that calculation, the age of 25 my was accepted by most Principles of Radiometric Dating.

The number of protons in the nucleus of an atom is called its atomic number. Furthermore, astronomical data show that radioactive half-lives in elements in stars billions of light years away is the same as presently measured,*radiometric dating formula*. The age can then be calculated from equation 1. Because argon is an inert gas, it is not possible that it might have been in the mineral when it was first formed from molten magma.
