Mercury Information

Heavy silvery liquid metallic element, belongs to the zinc group. Used in thermometers, barometers and other scientific apparatus. Less reactive than zinc and cadmium, does not displace hydrogen from acids. Forms a number of complexes and organomercury compounds.

Used in thermometers, barometers, and batteries. Also used in electrical switches and mercury-vapor lighting products.
