Also known as Pb, element 82
Lead () is a chemical element with the symbol Pb (from the Latin ) and atomic number 82. It is a heavy metal, denser than most common materials. Lead is soft, malleable, and has a relatively low melting point. When freshly cut or melted, it appears shiny silvery with a bluish tint, but tarnishes to dull gray on exposure to air. Lead has the highest atomic number of any stable element, and three of its isotopes are endpoints of major nuclear decay chains of heavier elements.
AI overview
Lead is a heavy metal element (symbol Pb) that is soft, malleable, and has a relatively low melting point, appearing silvery-blue when freshly cut but tarnishing to gray in air. It matters scientifically because it has the highest atomic number of any stable element and serves as the endpoint of major nuclear decay chains from heavier elements.
