Lead Element in Periodic Table | Atomic Number Atomic Mass


Lead Element:

Lead is the chemical element and it is a member of group 14 and period 6 in the periodic table. Atomic number of Lead is 82 and is indicated by symbol Pb. Lead is the heaviest member of the carbon family. It is a soft and silvery white and greyish metal. Lead occurs rarely in its native metallic form. Pb is generally found combined with sulphur. Lead is the 38th most abundant element in the crust. Its abundance is about 0.0013 per cent in the Earth's crust. Lead has 24 isotopes among which four  are stable such as 204Pb, 206Pb, 207Pb, and 208Pb.

Lead Element Uses:

  • Because of its properties like high density, low melting point, ductility and relative inertness to oxidation make it useful in construction, car batteries, plumbing, ammunition, cable sheathing, weights for lifting, weight belts for diving, lead crystal glass, radiation protection and in some solders.
  • Pbis often used to store corrosive liquids. It is also sometimes used in architecture, for roofing and in stained glass windows.
  • Pb is toxic to human body so there is no known biological use. If it  accumulates in the body, it can cause serious health problems.
