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

So, we have a “clock” which starts ticking the moment something dies.

Obviously, this works only for things which were once living.

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.

Familiar to us as the black substance in charred wood, as diamonds, and the graphite in “lead” pencils, carbon comes in several forms, or isotopes.

One rare form has atoms that are 14 times as heavy as hydrogen atoms: carbon-14, or C ratio gets smaller.

Radioactive dating uses the ratios of isotopes and their specific decay products to determine the ages of rocks, fossils and other substances.

Elements occur naturally in the earth, and they can tell us a lot about our Earth's past.

Radioactive dating is a method of dating rocks and minerals using radioactive isotopes.
