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.
