Radiometric dating is possible if a rock contains


Since all atoms of the same element have the same number of protons, different nuclides of an element differ in the number of neutrons they contain.

For example, hydrogen-1 and hydrogen-2 are both nuclides of the element hydrogen, but hydrogen-1's nucleus contains only a proton, while hydrogen-2's nucleus contains a proton and a neutron.

Radiometric dating methods are the strongest direct evidence that geologists have for the age of the Earth.

All these methods point to Earth being very, very old -- several billions of years old.

Uranium-238 contains 92 protons and 146 neutrons, while uranium-235 contains 92 protons and 143 neutrons.

To keep it short, a nuclide is usually written using the elements abbreviation.

I found several good sources, but none that seemed both complete enough to stand alone and simple enough for a What is radiometric dating?


Young-Earth creationists -- that is, creationists who believe that Earth is no more than 10,000 years old -- are fond of attacking radiometric dating methods as being full of inaccuracies and riddled with sources of error.

When I first became interested in the creation-evolution debate, in late 1994, I looked around for sources that clearly and simply explained what radiometric dating is and why young-Earth creationists are driven to discredit it.

Protons and neutrons together are called nucleons, meaning particles that can appear in the atomic nucleus.

A nuclide of an element, also called an isotope of an element, is an atom of that element that has a specific number of nucleons.

The rules are the same in all cases; the assumptions are different for each method.

To explain those rules, I'll need to talk about some basic atomic physics. Hydrogen-1's nucleus consists of only a single proton.
