Hg is the chemical symbol for the element mercury. Mercury is a heavy, silvery-white metal that is liquid at room temperature. It is commonly known as quicksilver. Mercury is a unique element because it is the only metal that is liquid at room temperature. It has a high density and is a poor conductor of heat, but a good conductor of electricity.
