Lead is a chemical element, its chemical symbol is Pb(Latin Plumbum; lead, with an atomic number of 82, is the largest non-radioactive element by atomic weight.
Lead is a soft and malleable weak metal, toxic, and a heavy metal. The original color of lead is bluish-white, but in the air the surface is soon covered by a dull gray oxide. It can be used in construction, lead-acid batteries, warheads, artillery shells, welding materials, fishing gear, fishing gear, radiation protection materials, trophies and some alloys, such as lead-tin alloys for electronic welding. Lead is a metallic element that can be used as a material resistant to sulfuric acid corrosion, ionizing radiation, batteries and so on. Its alloy can be used for type, bearing, cable cover, etc., and can also be used for sports equipment shot.
