What is Lead?
- Lead is an element of the periodic table with an atomic number of 82.
- Lead (Pb) is a metal which has been used by humans for centuries dating back to 7000 BC.
- The element is present in various minerals in minute quantities excluding sulphide and lead glance(PBS) which is used to produce the metal around the world.
Uses of Lead
- It is a metal that has been used since Roman times for making paints and pipes as a corrosion resistant.
- Used in car batteries and a major ingredient of lead acid batteries.
- For soldering parts of electrical equipment.
- As electrodes in electrolysis processes.
Properties of Lead
- Lead (Pb) is a white lustrous metal with a soft texture and is highly malleable.
- The metal is highly corrosion resistant, in addition to not being a poor conductor of electricity.
- The metal in its powdered form produces a bluish-white flame when burnt in air.
- Once mixed with fluorine in room temperature forms lead fluoride.
Important Facts About Lead
- The metal element is hazardous for humans and would target the vital internal organs leading to several cases of lead poisoning.
- The metal is said to hamper the growth of organs and the brain of young children.
- Lead is one among a handful of elements which were known to the society from ancient times; thus, it was never formally discovered. In fact, alchemists considered lead as one of the oldest metals.
