Full Answer

Lead is dense, malleable and has a melting point of 621.5 degrees Fahrenheit (327.46 degrees Celsius). While this metal is highly resistant to corrosion, it is a poor conductor of electricity. Its chemical symbol Pb is derived from "plumbum," which is Latin for "lead." Minerals or ore, such as galena and cerrusite, contain lead. The earth’s crust contains approximately 0.0013 percent lead.

Lead and its alloys have many applications. It is used as a radiation shield for x-ray equipment, a sound absorber and a solder for electrical components. It is also used in the production of lead crystal and automobile batteries.

Lead can be toxic to humans and animals, and the instructions of the United States Environmental Protection Agency (EPA) should be followed to lower chances of any potential lead exposure.
