Alchemists called lead Saturn and used the symbol for the planet to designate Pb. Lead compounds, such as lead ash (PbO) and white lead [2PbC03. Pb(OH)2], were used in ancient Greece and Rome as constituents of medicines and dyes. With the invention of firearms, lead was used in ...

1.a heavy toxic bluish-white metallic element that is highly malleable: occurs principally as galena and used in alloys, accumulators, cable sheaths, paints, and as a radiation shield. Symbol: Pb; atomic no.: 82; atomic wt.: 207.2; valency: 2 or 4; relative density: 11.35; melting pt....
The periodic table is a chart that shows how chemical elements are related to each other. Although a member of the carbon family, lead looks and behaves very differently from carbon. Lead is one of only a few elements known to ancient peoples. One of the oldest examples of lead is a ...
