Lead is a chemical element with symbol Pb and atomic number 82. Classified as a post-transition metal, Lead is a solid at room temperature.

Lead is the element with the heaviest stable isotope, 208 Pb. (The more massive 209 Bi, long considered to be stable, actually has a half-life of 2.01×10 19 years.) A total of 43 lead isotopes are now known, including very unstable synthetic species. In its fully ionized state, the isotope 205 Pb also becomes stable.

The atomic mass of the element depends on the relative abundance of the isotopes. The mass spectrum has shown that lead has 4 isotopes. The mass of the isotopes and their intensity % are as follows: problem 99 asks you to use the mass spectrum of lead to estimate its atomic mass. So the first thing that we have to do is convert intensity percent, 2% abundance. Recall that what the mass spectrum actually shows you is the relative abundances of each isotope of a given element and the atomic mass of each of those isotopes. For lead 82 Pb 207 (atomic mass = 206.975880 u) obtain (a) the mass defect in atomic mass units, (b) the binding energy (in MeV), and (c) the binding energy per nucleon (in MeV). A look at how the relative atomic mass can be calculated from Mass Spectra.
