Quecksilber (Hg)

Ordnungszahl: 80
Name: Mercury
Namensursprung: From the Roman god Mercury; symbol from Latin: hydrargyrus (liquid silver).
Entdeckung: Known to the ancients.
Beschreibung: Heavy, silver-white metal, liquid at ordinary temperatures.
Vorkommen: Virtually all mercury comes from cinnabar or mercury sulfide (HgS). Some sources of red cinnabar are so rich in mercury that droplets of elemental mercury can be found in random samples.
Verwendung: Used in thermometers, barometers, and batteries. Also used in electrical switches and mercury-vapor lighting products.
