Properties of lead
Lead is a soft, malleable, ductile, bluish-white, dense metallic element, extracted chiefly from galena and found in ore with zinc, silver and copper.
Whilst it is still used for its malleability and corrosion resistance, it is its chemical properties that make it a thoroughly modern metal. Today’s uses are focused on power and protection: in radiation shielding, underwater power and communication cables, combustion engine and electric vehicle batteries and in batteries providing emergency power suppy.
