Mercury is used in making lights and batteries. Surface tension is a property of liquids that makes them act like they are covered with skin. There is in fact only another liquid element, bromine. Keywords: correlation, mercury, vapor pressure. J. Chem. In order to tip back and forth, the capsule may be made. In the 4th Century B.C. Mercury(II) fulminate, or Hg(CNO) 2, is a primary explosive.It is highly sensitive to friction, heat and shock and is mainly used as a trigger for other explosives in percussion caps and blasting caps. The element mercury is silver in colour. Mercury is a silvery-white, shiny metal, which is liquid at room temperature. The same amount has existed on the planet since the earth was formed. Chemical properties of Mercury 80 Hg Mercury 200.59 Period: 6 Melting Point: -39 Boling Point: 357 Ionization Energy: 10,4375 Electrone Gativity: 2,28 Covalenz Radius: 144 Discovery Year: ancient Inventor: Ramsay, Sir William & Strutt, John For enquiries, contact us. Mercury is a transition metal, where one of the elements found between Group 2 (IIA) and 13 (IIIA) on the periodic table. You will not receive a reply. Most common substances, like Mercury, exist as States of Matter as solids, liquids, gases and plasma. It has two physical properties of special interest. Its density is 13.59 grams per centimetre in cube. It can also be used in medicine. Safety Data Sheet Mercury (Metallic) SDS Revision Date: 05/01/2015 Page 3 of 9 4. Apart from thermometry, mercury is used as a reference standard for determining the volume of small capacity measures and to maintain the primary standard barometer. Introduction Recent concerns about mercury as an industrial pollutant have lead to increased interest in the detection and regulation of mercury in the environment [1]. The only other liquid … Kirk-Othmer Encyclopedia of Chemical Technology. A 20ml sample of mercury has a mass of 271g. 0 0. (Eggeman, Tim. Source(s): https://shrinke.im/a8wEu. Produced and studied for millennia, mercury's use has steadily declined since the 1980s as a result of greater attention to the negative health impacts that it has on humans and the environment. At room temperature, mercury is a thick, silvery liquid with a very high density and low heat conductivity. The density of mercury at 20 degree C to be 13545.848 kg/m3. Mercury metal has many applications. Never give anything by mouth to an unconscious person. Mercury dissolves to form amalgams with gold, zinc and many metals. (Concise international chemical assessment document ; 50) 1.Mercury - adverse effects 2.Mercury compounds - adverse effects 3.Risk assessment 4.Environmental exposure 5.Occupational exposure I.International Programme on Chemical Safety II.Series The chemical symbol for Mercury is Hg. The mercury runs from one end to the other as it tips. The Cinnabar releases mercury as a vapour when heated; later the vapour is cooled and captured as liquid mercury. Mercury Stability Hg is stable in glass (only borosilicate glass studied) in 5% nitric acid at room temperature at all concentrations studied ( 0.05 to 1000 µg/mL) for 1 year. In nature, mercury is rarely present as the pure, liquid metal, but rather in compounds and inorganic salts. Calculate the density of mercury. It is commonly known as quicksilver and is heavy, silvery-white liquid metal. Because iron is an exception to this rule, iron flasks have been traditionally used to trade mercury. Though the equation is simple one should be able to manipulate this equation so that one can connect this piece of information with other facts and formulas that are given in the passage. First aid measures 4.1. Chemical properties of Mercury: Mercury (chemical symbol Hg) is an amazing element. Many rivers and streams are polluted with mercury. Atomic number 80 Atomic weight 200.59 Melting point, °C −38.89 Boiling point at 101.3 kPa, … Mercury element in the periodic table is symbolized as Hg. The element's atomic mass is 200.59 grams per mole and its specific gravity is 13.5 times that of water. Besides quicksilver, an alternate name for this element is hydrargyrum. Acidic surface waters can contain significant amounts of mercury. The same amount has existed on the planet since the earth was formed. chemical properties, health and environmental effects of mercury. (1,2,7,9,10) Acrodynia may also occur from exposure to inorganic mercury compounds. Environment and health concerns. Mercury is a chemical element with the symbol Hg and atomic number 80.It is commonly known as quicksilver and was formerly named hydrargyrum. Mercury is a silvery-white, shiny metal, which is liquid at room temperature. Hg is stable in glass (only borosilicate glass studied) in 5% nitric acid at 4°C at 0.05 µg/mL for 14 months. The Mercuric oxide is used in skin ointments. Ammonia forms explosive compounds with gold, mercury, or silver. It is commonly known as quicksilver and was formerly named hydrargyrum (/ h aɪ ˈ d r ɑːr dʒ ər ə m / hy-DRAR-jər-əm). This is a preview of subscription content, log in to check access. The metal is a fair conductor of electricity, but a poor conductor of heat. Mercury is a very toxic substance and accumulates in the body. chemical properties, health and environmental effects of arsenic. Mercury (Hg) has a unique combination of physical properties. Mercury is a silvery-white shiny heavy liquid with stable chemical properties. Mercuric oxide, [solid] appears as red or orange-red odorless, dense crystalline powder or scales, yellow when finely powdered. Mercury is known to be a metallic element which is both univalent and bivalent. The Chemical Abstracts Service registry number is a unique identifier of a particular chemical, designed to prevent confusion arising from different languages and naming systems. In nature, mercury has 3 possible conditions of electrical charge, or valence states. Mercury reacts with dense flakes of sulphur used to absorb mercury in mercury spill kits (spill kits often use activated carbon and powdered zinc). The total electrical charge of the nucleus is therefore +Ze, where e (elementa… Mercury is used in barometers, manometers, thermometers, sphygmomanometers, mercury switches, float valves, mercury relays, fluorescent lamps and other instruments, while concerns about the toxicity of the element have led to mercury thermometers and sphygmomanometers being increasingly phased out in clinical settings in favour of alternatives such as glass thermometers and thermometers filled with alcohol or galinstan Similarly, mercury sphygmomanometers have replaced mechanical pressure gauges and electronic strain gauge sensors. Never give anything by mouth to an unconscious person. Thimerosal, which consists of approximately 50% mercury by weight, has been one of the most widely used preservatives in vaccines. 41:1048. The nucleus is composed of protons and neutrons. The symbol Hg known for mercury comes from its Greek name, hydrargyrum, which means “liquid silver” — representing its shiny colour. Mercury is a liquid metallic element of many useful applications. We have no idea who invented it. Mercuric sulfide (HgS) is reddish-orange in color. Mercury has a melting point of -38.9oC, a boiling point of 356.7oC, and is the only metal to remain in liquid form at room temperature. A more complete table of physical and chemical properties of some Hg compounds can be found in the Agency of Toxic Substances and Disease Registry (ATSDR) Toxicological Profile for Mercury (Update) (ATSDR 1999).
