The relative abundances of the four stable isotopes are approximately 1.5%, 24%, 22%, and 52.5%, combining to give a standard atomic weight (abundance-weighted average of the stable isotopes) of 207.2(1). Lead is the element with the heaviest stable isotope, 208 Pb.

Both the uranium-235 and uranium-238 series decay into an isotope of lead. The half-life of converting 235 U to 207 Pb is 710 million years, and the half-life of converting 238 U to 206 Pb is 4.47 billion years. Because of high resolution mass-spectroscopy, both chains can be used to date rocks, giving complementary information about the rocks.
The 4 stable isotopes of 82Pb lead have the atomic numbers 204, 206, 207, and 208. In this area of the periodic table the stable elements can be organized with relationship to some stability trend lines having the formula as follows: A = 3Z - an even number. Accordingly, these stable lead isotopes can be organized as follows:
The δ values and absolute isotope ratios of common reference materials are summarized in Table 1 and described in more detail below. Alternative values for the absolute isotopic ratios of reference materials, differing only modestly from those in Table 1, are presented in Table 2.5 of Sharp (2007) [1] (a text freely available online), as well as Table 1 of the 1993 IAEA report on isotopic ...
Lead consists of four stable isotopes: 204 Pb, 206 Pb, 207 Pb, and 208 Pb. Local variations in uranium/thorium/lead content cause a wide location-specific variation of isotopic ratios for lead from different localities. Lead emitted to the atmosphere by industrial processes has an isotopic composition different from lead in minerals.

Natural lead consists of four stable isotopes with mass numbers of 204, 206, 207, and 208, [38] and traces of six short-lived radioisotopes with mass numbers 209–214 inclusive. The high number of isotopes is consistent with lead's atomic number being even.
