. About PB (lead) 1. Atomic number is 82, element symbol is Pb 2. One of the seven major metals used by ancient humans. 3. It is soft and easy to process. 4. We use 10 million tons per year worldwide 5. It is Reusable

. PB’s properties 1. Lead is a bluish white metal. 2. Conductivity is 4.56∗10 6 mhos/m 3. Melting Point is 327.46oC and Boiling Point is 1749oC 4. Density is 11.34g/cm3 5. Mohs hardness is 1.5

. Usage of Pb Lead is used as a lead-acid battery because of its high electrical conductivity 2. Lead has high electrical conductivity and low melting point and is used for soldering. 3. Lead is used as a soft plate because of its high ductility and ductility, easy to process and highly corrosion resistant (1) (2) (3)
