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 bromine, though metals such as caesium, gallium, and rubidium melt just above room temperature.ercury(II) oxide, the main oxide of mercury, arises when the metal is exposed to air for long periods at elevated temperatures. It reverts to the elements upon heating near 400 Â°C, as was demonstrated by Joseph Priestley in an early synthesis of pure oxygen.
Because of its toxicity, the clinical use of mercury and mercurials is diminishing. Mercury is an element with atomic symbol Hg, atomic number 80, and atomic weight 200.59; a heavy, silvery-white metal, liquid at room temperature, a rather poor conductor of heat and a fair conductor of electricity.
