The half-life is so predictable that it is also referred to as an atomic clock.

Can you guess how much uranium-238 would remain after the passing of another half-life?

Just as in the example with uranium, scientists are able to determine the age of a sample by using the ratios of the daughter product compared to the parent.

Also, when dating with carbon-14, scientists compare the amount of carbon-14 to carbon -12.

Radioactive dating enables geologists to record the history of the earth and its events, such as the dinosaur era, within what they call the geologic time scale.An isotope is a variation of an element based upon the number of neutrons.The disintegration of the neutrons within the atom of the element's nucleus is what scientists call radioactivity.An isotope disintegrates at a constant rate called the half-life --the time it takes for half the atoms of a sample to decay. By counting the number of half-lives and the percentages remaining of parent and daughter isotopes, scientists are able to determine what they call the absolute age of a discovery.Carbon-14 is a specific isotope used in dating materials that were once living.Carbon, uranium and potassium are just a few examples of elements used in radioactive dating.Each element is made up of atoms, and within each atom is a central particle called a nucleus.Other common isotopes used in radioactive dating are uranium, potassium and iodine.To answer the question to the uranium problem above, after about three half-lives, only 12.5% of uranium-238 would remain.
