Elemental lead is a soft, highly malleable and ductile metal that is insoluble in water.[2] Lead rarely exists naturally in its pure form.[3] It is typically found in low concentrations in the earth???s crust as the mineral galena (lead sulfide).[3] Lead forms both inorganic and organic compounds with many substances, including acetate, arsenic, antimony, chlorine, oxygen, and phosphate.[4] There
