1. (Elements & Compounds) 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...
Lead: descriptionYour user agent does not support the HTML5 Audio element. Lead is a bluish-white lustrous metal. It is very soft, highly malleable, ductile, and a relatively poor conductor of electricity. It is very resistant to corrosion but tarnishes upon exposure to air. Lead pipes bearin...
3. Over time, "plumbum" evolved to specifically refer to the element we now know as lead.4. Consequently, the symbol for lead in the periodic table is represented by "Pb," a carryover from its historical Latin nomenclature.
