Lead (pronounced "led") is a chemical element; it has symbol Pb (from Latin plumbum) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue.
Metals such as α-iron (Fe) (ferrite), chromium (Cr), vanadium (V), molybdenum (Mo), and tungsten (W) possess BCC structures. These BCC metals have two properties in common, high strength and low ductility (which permits permanent deformation).
Lead is the 82nd element in the periodic table and has a symbol of Pb and atomic number of 82. It has an atomic weight of 207.2 and a mass number of 208. Lead has eighty-two protons and one hundred twenty-six neutrons in its nucleus, and eighty-two electrons in six shells.
