The team at periodicvideos has created a TED-Ed Lesson for every element of the periodic table. This one is about element number 82. Special submarines and heavy-duty glass -- learn all about lead in this lesson.
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.
