Mercury is a natural element (number 80 on the Periodic Table) named after the Roman god of trade, profit, and commerce. Under normal conditions, mercury is a shiny liquid metal. Itâ€™s known for its strange fluid movements; some you may recognize from scenes in Terminator 2 for the liquid metal T-1000.
Mercury is commonly used in thermometers, barometers, fluorescent lamps, and batteries. Itâ€™s also been used as a coolant for nuclear reactors, a propellant for early ion engines, and in new types of atomic clocks.
