Lead

Description

 

Lead is a main-group element. It is also counted as one of the heavy metals. It is used in building construction, lead-acid batteries, bullets and shots, weights, as part of solders, pewters, fusible alloys and as a radiation shield. It is also used as electrodes in the process of electrolysis. Lead compounds are used as a coloring element in ceramic glazes, notably in the colors red and yellow. It is frequently used in polyvinyl chloride plastic, which coats electrical cords. Lead, at certain exposure levels, is a poisonous substance to animals. It damages the nervous system and causes brain disorders. Excessive lead also causes blood disorders in mammals. It is restricted under the RoHS directive.
