is a chemical element in the periodic table that has the symbol Hg (Latinized hydrargyrum, meaning watery or liquid silver) and atomic number 80. A heavy, silvery transition metal, mercury is one of five elements that are liquid at or near standard room temperature (the others are the metals caesium, francium, and gallium, and the nonmetal bromine). Mercury is used in thermometers, barometers and other scientific apparatus, although the use of mercury in thermometers has been largely phased out in clinical and scientific environments (in favor of alcohol-filled, digital or thermistor-based replacements) due to concerns about the element's toxicity. Mercury is still used in dental amalgam. Mercury is mostly obtained by reduction from the mineral cinnabar. Mercury, like lead, is a neurotoxin, and elevated blood mercury levels have led to retardation and deformities in children.

Hmm, mercury. I think I know a few things about mercury that can help you out. Not only is it high in density and silvery, it's also very heavy. If you had filled a 20 oz. bottle with it, it could very well weigh more than five or six pounds. Even though some thermometers and thermostats use it, it is highly poisonous. You do NOT want this to come in contact with your skin. It's basically liquid metal.
Hope that helps you out somehow.

element 80 of the periodic table
the only liquid metal at room temperature
High density 13.6 g /cm^3
precipitates with chloride anions
has a valence of 1 or 2
One of the most violent toxic even at small dosis forming a complx called methlmercury

Chevyeagle is overall correct, but he forgot to specify that mercury is a liquid at room temperature. It is sold in 76-lb amounts in iron flasks. Iron is one of the few metals that mercury cannot dissolve.
