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 is the third element in the twelfth column of the periodic table. It is classified as a transition metal. Mercury atoms have 80 electrons and 80 protons with 122 neutrons in the most abundant isotope. Characteristics and Properties. Under standard conditions mercury is a shiny, heavy, silvery liquid.
