Silver Liquid Mercury for Laboratory

Mercury, which usually appears as a thick silvery fluid, is the only metal that's liquid at room temperature. Its elemental symbol is Hg, which comes from the Greek word “hydrargyrum,” meaning “liquid silver.” In fact, it's also called quicksilver
It was also commonly used in batteries, fluorescent lights, felt production, thermometers and barometers. Again, these uses have been phased out. Mercury easily forms alloys, called amalgams, with other metals such as gold, silver and tin.
