Best Answer: lead is found in archeological digs dating over 5000 years ago which means that people knew how to refine it before the pyriamid in Egypt were built. IT was probably discovered by accident when people built it a very hot fire for cooking and it melted the lead that was in the rocks. The mineral that contains lead is galena is commonly found around the world.
Lead (/lÉd/) is a chemical element in the carbon group with symbol Pb (from Latin: plumbum) and atomic number 82. Lead is a soft, malleable and heavy post-transition metal. Metallic lead has a bluish-white color after being freshly cut, but it soon tarnishes to a dull grayish color when exposed to air.Lead has a shiny chrome-silver luster when it is melted into a liquid. It is also the heaviest non-radioactive element (some radioactive elements, like technetium, are lighter).ead has only one common allotrope, which is face-centered cubic, with the length of an edge of a unit cell being 349 pm. At 327.5 Â°C (621.5 Â°F), lead melts; the melting point exceeds that of tin (232 Â°C, 449.5 Â°F), but is significantly below that of germanium (938 Â°C, 1721 Â°F).
