An atom with the same number of protons in the nucleus but a different number of neutrons is called an isotope.

Understand how decay and half life work to enable radiometric dating.

The rate of decay (given the symbol λ) is the fraction of the 'parent' atoms that decay in unit time.

For geological purposes, this is taken as one year.

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.

After one half-life has elapsed, one half of the atoms of the nuclide in question will have decayed into a "daughter" nuclide, or decay product.
