Element Story - Lead

Lead is an element with atomic number 82, belonging to Group 14. It is a soft, heavy, bluish-gray metal that is easy to work with and has a relatively low melting point of approximately 327°C. In air, a protective layer forms on its surface, making it quite resistant to corrosion, and it also has the property of absorbing radiation well. Due to these characteristics, lead is used in battery electrodes, radiation shielding, cable sheathing, and some building materials. In the past, lead was used in paints, gasoline additives, and water pipes, but because lead and its compounds are toxic heavy metals harmful to the human body, many uses are now restricted. In nature, it is primarily obtained from the mineral galena, which is lead sulfide. Lead is also ultimately produced during the decay process of radioactive elements like uranium and thorium. In fact, some isotopes of lead appear as stable end products in the decay series of radioactive elements. In the universe, lead is formed through stellar nucleosynthesis and neutron capture processes, and it is an important heavy element produced particularly in the s-process, a slow neutron capture process.
