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.
Mercury, Hg 2+, Hg 2 2+ Most common oxidation states: +1, +2. M.P.-38.87 o. B.P. 356.57 o. Density 13.546 g/cm 3. Characteristics: Mercury is one of the few liquid elements. It dissolves in oxidizing acids, producing either Hg 2+ or Hg 2 2+, depending on which reagent is in excess. The metal is also soluble in aqua regia ( a mixture of hydrochloric and nitric acids) to form HgCl 4 2-.
