Metallic chemical element, chemical symbol Pb, atomic number 82.

Lead is a soft, silvery white or grayish, malleable, ductile, dense metal that conducts electricity poorly. Its stable isotopes are all end products of radioactive decay of uranium and other heavy elements. Known since ancient times, lead is so durable and resistant to corrosion that Roman lead pipes are still usable. Lead is used in roofing, as cable coverings, and in pipes, conduits, and structures. Other uses are in storage batteries, ammunition, and low-melting-point alloys (e.g., solder, pewter) and as shielding against sound, vibrations, and radiation. Lead is rarely found free in nature; its major ore is the sulfide galena (PbS). Because it and its compounds are poisons (see lead poisoning), lead-based paints and gasoline additives have been phased out in many countries. Lead in compounds has valence 2 and 4; an oxide (litharge, PbO) is the most widely used. Lead compounds are added to lead crystal (see glass), glazes, and ceramics and are used as pigments, drying agents for paints and varnishes, insecticides and herbicides, and fireproofing agents and in matches, explosives, and pyrotechnics. Almost half of all lead is recovered from recycled scrap. The "lead" in pencils is graphite.

 city, Lawrence county, western South Dakota, U.S. It lies in the northern Black Hills, about 40 miles (65 km) northwest of Rapid City, at an elevation of 5,280 feet (1,609 metres). Situated just southwest of Deadwood, it is built on the steep inclines of the hills. It was established in 1876 following the discovery of gold (gold rush) by Fred and Moses Manuel, and its name was inspired by the lode mines in the area, an outcrop of ore being termed a “lead.” Lead was South Dakota's largest city at the time of statehood in 1889. The city lost a major aspect of its economy with the closing of the Homestake Gold Mine (opened 1876), which was the world's oldest continuously operating gold mine until it closed in 2001; chemist Raymond Davis (Davis, Raymond, Jr.) received the 2002 Nobel Prize for Physics for his work in detecting neutrinos in a laboratory in the mine. Tourism, based primarily on the more than 80 gambling halls in Deadwood (where gambling was legalized in 1989), is now an economic mainstay. Some ranching and lumbering also take place in the area. Lead is surrounded by Black Hills National Forest and has many outdoor recreational opportunities, including two ski areas. The Black Hills Mining Museum has a simulation of an underground gold mine. Inc. 1890. Pop. (1990) 3,632; (2000) 3,027.
