Lead (Pb) is a soft gray metal that has the atomic number 82 in the periodic table in Group 14. It has the symbol Pb. Lead as a metal has been known about since Roman times where it was used to make coins and utensils as well as in plumbing. It was called Plumbum hence the symbol Pb.

, showing natural variations in the atomic weight of lead ranging from 207.184 to 207.293. The Commission assigned the annotation “r” to lead
Thus the atomic weight of lead is 207.2 g/mol, as mentioned earlier in the discussion. An important corollary to the existence of isotopes should be emphasized at this point.

Lead's close-packed face-centered cubic structure and high atomic weight result in a density of 11.34 g/cm 3, which is greater than that of common metals such as iron (7.87 g/cm 3), copper (8.93 g/cm 3), and zinc (7.14 g/cm 3).

He also predicted that the lead produced by the disintegration of uranium would have an atomic weight 206, while that of the lead produced from thorium would be 208, and that consequently the atomic weight of the lead found in uranium minerals should be less than that of ordinary lead (207.2) while that of lead from thorium minerals should be greater.
