What is Lead?
Lead is a type of metal found on the periodic table. It's known by the symbol Pb and has the atomic number 82. People have been using lead since about 7000 BC, mainly extracted from minerals like lead sulphide (PbS).

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.

Frequently Asked Questions on Lead
Lead is used in batteries, radiation shielding, and as a component in some alloys like solder.
Lead is classified as a metal because it has metallic properties such as conductivity and malleability
Lead is soft and dense, making it useful in various applications, but it's toxic to humans and the environment.
Lead is a post-transition metal known for its low melting point and high density.
Lead is represented by the chemical symbol Pb on the periodic table.
The symbol Pb comes from the Latin word "plumbum," which means lead.
Lead typically forms ions with a charge of +2 due to its electronic configuration.
Lead can have a +2 oxidation state because it readily loses two electrons to achieve a stable configuration.
Tin and lead both have a valency of +2 in most of their common compounds.
Bromine (Br) typically has a valency of -1, as it tends to gain one electron to achieve a stable configuration.
