What the name means: The word lead probably comes from the Anglo Saxon word laedan. The symbol, Pb, derives from the Latin word for lead, plumbum.
Who identified lead?: Lead was one of the first metals to be worked by man. Jewelry containing lead and dating from 6500BC has been unearthed in Turkey. The Romans mined lead in Iberia and used it to make pipes and pewter (an alloy of copper and lead). The alchemists saw lead as particularly significant because it was considered the "oldest metal". They used it in complex recipes, often kept secret, in an attempt to make gold.
STP = standard temperature and pressure.
About lead: Lead is a grey, soft and ductile metal that is not very strong. It is resistant to corrosion. Lead can be found as the element in nature but this is quite rare; it is extracted from its compounds from ores, such as galena.
