Scientists use a technique called radiometric dating to estimate the ages of rocks, fossils, and the earth.

For example, all carbon atoms have 6 protons, all atoms of nitrogen have 7 protons, and all oxygen atoms have 8 protons.

The number of neutrons in the nucleus can vary in any given type of atom.
