Lead is a chemical element with symbol Pb (from Latin: plumbum) and atomic number 82. Lead is a soft, malleable and heavy post-transition metal. Metallic lead has a bluish-white color after being freshly cut which guradually turns to a dull grayish color when exposed to air. Lead has a shiny chrome-silver luster when it is melted into a liquid. It is also the heaviest non-radioactive element. lead Ore is available as Lead oxide or lead sulphite in nigeria.
Lead is used in building construction, lead-acid batteries, bullets and shot, weights, as part of solders, pewters, sible alloys, and as a radiation shield. Lead has the highest atomic number of all of the stable elements, although the next higher element, bismuth, has one isotope with a half-life that is so long (over one billion times the estimated age of the universe) that it can be considered stable. Lead's four stable isotopes have 82 protons, a magic number in the nuclear shell model of atomic nuclei. The isotope lead-208 also has 126 neutrons, another magic number, and is hence double magic, a property that grants it enhanced stability: lead-208 is the heaviest known stable isotope.
If ingested, lead is poisonous to animals and humans, damaging the nervous system and causing brain disorders. Excessive lead also causes blood disorders in mammals. Lead is a neurotoxin that accumulates both in soft tissues and the bones. Lead poisoning has been documented from ancient Rome, ancient Greece, and ancient China.
Lead ore is abundant in Nigeria especially in Plateau state, Ebonyi state, Taraba State. Most Lead ore gotten from Nigeria usually contain between 35% to 75% lead and are usually packed in 50kg bags. Lead ore in Nigeria usually have some traces of silver metal and a sizeable quantity of Zinc in it.
