A riveting Lead design. Lead is a chemical element with atomic number 82 and symbol Pb (from Latin: plumbum). It has the second highest atomic number of all practically stable elements. As such, lead is located at the end of some decay chains of heavier elements, which in part accounts for its relative abundance: its stability exceeds those of other similarly-numbered elements.
