Uses of Lead
Lead has been used for a long time to make things like paint and pipes resistant to rust. It's also a big part of car batteries and is used in soldering electrical equipment and in certain chemical processes.
Properties of Lead
Lead is a soft, shiny metal that can be easily shaped. It's really good at resisting damage from things like rust, and it doesn't conduct electricity very well. When it's burned, it makes a blue-white flame, and if you mix it with fluorine, it becomes lead fluoride.
