Lead metal is known since ancient times and was widely used then. This often caused big sanitary problems, because lead compounds are quite toxic. 208Pb is the last stable isotope in the periodic table and it is also the end of the thorium decay chain. Therefore lead metal is quite abundant for an element with such a high number. Lead metal is a shiny-grey, very heavy and soft material with a low melting point. Amongst others, it is used for weights and for radiation protection. Lead metal reacts slowly with the air and quickly forms a protecting oxide layer, which makes it dark.
