Lead and zinc

By: Peter Russell and Tharsika Tharmanathan

Lead

Lead is a very soft, bluish-gray, metallic element. Since it is so soft, lead is usually alloyed with other elements. Water pipes in ancient Rome, some of which still carry water, were made of lead. The English word plumber and pluming are derived from the Latin word for lead, plumbum. The properties of lead which make it an excellent material for many applications are its density, high level of stability, and it has high degree of flexibility, which makes it easy to work.
