WebElemental mercury or metallic mercury is the element in its pure, ‘un-combined’ form. It is a shiny, silver-white metal that is liquid at room temperature, but is rarely found in this form in nature. If not sealed off, mercury slowly evaporates into the air, forming a vapour. The quantity of vapour formed increases as temperatures rise. http://flettresearch.ca/hgsampling.html
