Lead, symbolized as Pb, is a soft, heavy, and malleable metal with a dull gray appearance. Known for its high density and resistance to corrosion, it is widely used in batteries, radiation shielding, and as a component in alloys. Historically used in paints and pipes, its usage has been reduced due to toxicity concerns. Despite its health risks, lead remains vital in industries like construction, electronics, and automotive due to its durability and excellent shielding properties.
