Cinnabar would yield up its mercury simply on heating in a crucible, and the metal fascinated people because it was a liquid that would dissolve gold. The ancients used in on a large scale to extract alluvial gold from the sediment of rivers. The mercury dissolved the gold which could be reclaimed by distilling off the mercury.


It is also a chronic pollutant and mercury concentrates in animal/fish tissues in increasing amounts up the food chain. Characteristics: Mercury is a dense, silvery-white, poisonous metal with a mirror-like appearance. It is the only common metal that is liquid at room temperature. Mercury evaporates slowly at room temperature.


A heavy, silvery d-block element, mercury is the only metallic element that is liquid at standard conditions for temperature and pressure; the only other element that is liquid under these conditions is the halogen bromine, though metals such as caesium, gallium, and rubidium melt just above room temperature.


The element Mercury is named for the Roman god Mercury. Mercury is the only element to retain its alchemical name as its modern common name. The element was known to ancient civilizations, dating back to at least 2000 BC. Vials of pure mercury have been found in Egyptian tombs from the 1500s BC.


Mercury fulminate, Hg(CNO) 2, is used as a detonator. Mercury in the environment. Mercury occurs uncombined in nature to a limited extent. It rarely occurs free in nature and is found mainly in cinnabar ore (HgS) in Spain, Russia, Italy, China and Slovenia. World production of mercury is around 8.000 tonnes per year.


Facts about Mercury the Element 2: Characteristics. A heavy, shiny, silvery are the characteristics of mercury. At room temperatures, the only metal that is liquid is mercury. Because the other elements such as gallium, caesium, and rubidium are liquid just above room temperature. Besides, mercury can be gained with reduction from the mineral ...

Facts About Mercury (Hg) ... Mercury is a very toxic element. It can enter the body through an open wound or by inhaling or ingesting it. It can then cause damage to nerves, the liver and the ...


Mercury: chemical properties. Like cadmium, zinc and lead, mercury is a naturally occurring element known as a "heavy metal" and can be toxic to living organisms. The element's atomic mass is 200.59 grams per mole and its specific gravity is 13.5 times that of water.


Over 40% of Mercury’s volume is occupied by its core, 42% to be exact. The core is about 3,600 km in diameter. That makes Mercury the second most dense planet amongst our eight.
