Is PB&J good for runners?

Lead is a chemical element with the symbol Pb 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. It tarnishes to a dull gray color when exposed to air.



Why the lead symbol is Pb?

Lead's symbol Pb originates from its Latin name, plumbum — which actually used to refer to soft metals more generally.
