Free 5-day trial Radiometric dating is used to estimate the age of rocks and other objects based on the fixed decay rate of radioactive isotopes.

Learn about half-life and how it is used in different dating methods, such as uranium-lead dating and radiocarbon dating, in this video lesson. As we age, our hair turns gray, our skin wrinkles and our gait slows.

This decay process leads to a more balanced nucleus and when the number of protons and neutrons balance, the atom becomes stable.

This radioactivity can be used for dating, since a radioactive 'parent' element decays into a stable 'daughter' element at a constant rate.

The thing that makes this decay process so valuable for determining the age of an object is that each radioactive isotope decays at its own fixed rate, which is expressed in terms of its half-life.However, because of severe dating problems which are seldom mentioned, this alleged sequence cannot be maintained.To present the fossil evidence as a relatively smooth transition leading to modern humans is akin to intellectual dishonesty.However, first the ridiculous statement that the presenter declared she wanted another Atomic bomb to be dropped in order to engage her miniscule science knowledge is ridiculous. C14 is one molecule that is tested, we work with lots of carbon, C12, C13.... I haven't read all the comments so please excuse me if this has been ranted on before.Please note that the C-14 isotope has been around since the dawn of time.
