Mercury is a transitional element in the Periodic Table. It is a metal, and one of only six elements that is liquid at room temperature, and the only metal that is liquid under room temperature. It is liquid between -38 celsius and 357 celsius. It is extremely toxic to people, absorbed through the skin and digestive tract. It is commonly used in thermometers, barometers and other scientific apparatus - although this has been halted in some areas due to its toxicity. It is also used in lighting - if a current is passed through mercury vapour in a phosphor tube, it will emit a visible light, much like neon.
