Lead (82 Pb) has four stable isotopes: 204 Pb, 206 Pb, 207 Pb, 208 Pb. Lead-204 is entirely a primordial nuclide and is not a radiogenic nuclide. The three isotopes lead-206, lead-207, and lead-208 represent the ends of three decay chains: the uranium series (or radium series), the actinium series, and the thorium series, respectively; a fourth decay chain, the neptunium series, terminates ...

The nuclear notation #""_82^206"Pb"# gives us the mass number, 206, for this isotope of lead, and the atomic number of lead, 82. The atomic number of any isotope of any element is the number of protons in its atomic nucleus. So any atom of lead-206 has #82# protons. However, different isotopes have different numbers of neutrons.
