Explain how radioactive dating works

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.

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

So an atom of potassium-40 (K40), atomic number 19 can absorb an electron to become an atom of argon-40 (Ar40), atomic number 18.

The half-life of a radioactive nuclide is defined as the time it takes half of a sample of the element to decay.

Fossils are generally found in sedimentary rock — not igneous rock.

Protons and neutrons together are called nucleons, meaning particles that can appear in the atomic nucleus.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.I found several good sources, but none that seemed both complete enough to stand alone and simple enough for a What is radiometric dating?A third, very rare type of radioactive decay is called electron absorption.In electron absorption, a proton absorbs an electron to become a neutron.

Simply stated, radiometric dating is a way of determining the age of a sample of material using the decay rates of radio-active nuclides to provide a 'clock.' It relies on three basic rules, plus a couple of critical assumptions.
