Lead oxide crystals,coloured scanning electron micrograph (SEM). Lead is a heavy,soft,ductile metal that,under normal conditions,does not react with water. However,when it comes into contact with moist air,its reactivity with water increases. A small lead oxide (PbO) layer forms at the surface of the metal,seen here as leaf-like crystals.
