 Hg

English:  Mercury
French: Mercure
Croatian: Živa
German: Quecksilber
Italian: Mercurio


Atomic number: 80
Group numbers: 12
Period: 6
Standard state (20 °C): liquid

Mercury has been known since ancient times. The origin of the name comes from the Latin word hydrargyrum meaning liquid silver. It is heavy, silver-white metal, liquid at ordinary temperatures. Stable in air and water. Unreactive with alkalis and most acids. Gives off poisonous vapour. Chronic cumulative effects.

Mercury only rarely occurs free in nature. The chief ore is cinnabar or mercury sulfide (HgS). Used in thermometers, barometers and batteries. Also used in electrical switches and mercury-vapour lighting products. The price of 99.998 % pure redistilled mercury metal is 54.90 € for 450 g. 79Au <= 80Hg => 81Tl ___________________ If you have comments, corrections or suggestions about this site, please send me a e-mail.
