Lead is a soft and malleable metal belonging to the carbon group. It is the heaviest non-radioactive element which occurs naturally on earth in the form of four isotopes: lead-208, 207, 206, and 204. It is generally found in ores with copper, silver and zinc and is extracted ... Read more
Lead is a heavy metal and has several useful mechanical properties including high density, low melting point, ductility, and relative inertness. Lead is a chemical element with the atomic number 82. It has the highest atomic number of any stable element. Lead is soft and malleable, and has a relatively low melting point. When freshly cut, lead is bluish-white; it tarnishes to a dull gray color when exposed to air. Lead is weak and has metallic character which is illustrated by its amphoteric ... Read more
