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 (element) is a chemical element with symbol Hg and atomic number 80. It is commonly known as quicksilver and was formerly named hydrargyrum (/haÉªËdrÉrdÊÉrÉm/). On the periodic table of elements, the chemical symbol for mercury is Hg, from the Latin word-Hydrargyrum-meaning liquid silver. 2  For quite some time, we have known that high concentrations of mercury can be toxic to humans; the first account of mercury poisoning was recorded as early as 50 B.C.
