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 a silvery-white metal element that is liquid at ordinary room temperature; it has no taste or smell. It occurs as metallic mercury (Hg), as cinnabar (HgS) and in perhaps 25 other in organic mineral compounds. The elemental form (Hg) vaporizes at any temperature down to almost 40Â° below zero. The vapor also has no taste or smell. The specific gravity of mercury is 13.546; therefore, it is heavier than lead and, like lead and other heavy metals, it is a potent poison. Exposure to metallic mercury or mercury compounds, even in small quantities over a period of time, can cause severe poisoning.
