Lead is a chemical element in the carbon group with symbol Pb and the atomic number is 82. It has the highest atomic number of all the stable elements. It is soft and malleable but there are different types. For example, there’s metallic lead which has a bluish-white color but it tarnishes easily. Lead has a shiny chrome-silver luster when melted. It is commonly used in building construction, bullets, weights, etc.
Lead is a common element, it is easily found. It has been mined in the earth forever, that’s why it is impossible to say who actually discovered it. All we know is that it was discovered 7000 bc. It was also used in many different countries during the middle ages.
Lead has four stable isotopes, but many other isotopes. Some are naturally occurring. Lead 204 is entirely a primordial nuclide. Each isotope has an primordial nuclide. Several lead isotopes have been used as target in the production of superheavy elements. Lead isotopes can be used for developing chronologies in saltmarsh sediments.
