It is a heavy, silvery-white liquid metal. Mercury does not combine with oxygen to produce mercury (II) oxide, HgO, at a useful rate until heated to the range of 300 to 350 °C (572 to 662 °F). Mercury is a compound that can be found naturally in the environment. These alloys are called amalgams. It can be found in metal form, as mercury salts or as organic mercury compounds. Mercury (Hg) is a naturally occurring metal. The metal is a fair conductor of electricity, but a poor conductor of heat. In fact, there is only one other liquid element, bromine. Most of the mercury released from human activities is released into air, through fossil fuel combustion, mining, smelting and solid waste combustion. Mercury is a chemical element with the symbol Hg and atomic number 80. It is a rather poor conductor of heat if compared with other metals but it is a fair conductor of electricity. Mercury is commonly known as quicksilver and was formerly named hydrargyrum. Mercury from soils can accumulate in mushrooms. Some of the health effects exposure to mercury may cause include: irritation to the eyes, skin, and stomach; cough, chest pain, or difficulty breathing, insomnia, irritability, indecision, headache, weakness or exhaustion, and weight loss. Mercury metal has many uses. 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). Mercuric oxide is used in skin ointments. 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). Mercury is a chemical element with the symbol Hg and atomic number 80. The atom consist of a small but massive nucleus surrounded by a cloud of rapidly moving electrons. Mercury is the only common metal which is liquid at ordinary temperatures. Mercuric chloride (corrosive sublimate, HgCl2) is used as an insecticide, in rat poison, and as a disinfectant. Mercury fulminate, Hg(CNO)2, is used as a detonator. Mercuric sulfide (HgS) is reddish-orange in color. Still mercury concentrations in the environment are increasing; this is ascribed to human activity. Metallic mercury is used in a variety of household products, such as barometers, thermometers and fluorescent light bulbs. Mercury is also found in two positively charged, or cationic, states, Hg2+ (mercuric) and Hg1+(mercurous). It reacts with some acids when they are hot, but not with most cold acids. Hazard Summary Mercury exists in three forms: elemental mercury, inorganic mercury compounds (primarily mercuric chloride), and organic mercury compounds (primarily methyl mercury). Droplets of liquid mercury are shiny and silver-white with a high surface tension, appearing rounded when on flat surfaces. The abundance of mercury in the Earth's crust is estimated to be about 0.5 parts per million. Chemical properties. Mercury(II) chloride or mercuric chloride (historically "corrosive sublimate") is the chemical compound of mercury and chlorine with the formula HgCl 2.It is white crystalline solid and is a laboratory reagent and a molecular compound that is very toxic to humans. Mercury compounds have many uses. Refer to the article on Mercury Element for additional information and facts about this substance. The most important mercury salts are mercuric chloride HgCl2 (corrosive sublimate - a violent poison), mercuric chloride Hg2Cl2 (calomel, still used in medicine occasionally), mercury fulminate (Hg(ONC)2, a detonator used in explosives) and mercuric sulphide (HgS, vermillion, a high-grade paint pigment). This can cause harmful effects, such as nerve, brain and kidney damage, lung irritation, eye irritation, skin rashes, vomiting and diarrhoea. Most common substances, like Mercury, exist as States of Matter as solids, liquids, gases and plasma. It is commonly known as quicksilver and is heavy, silvery-white liquid metal. The chemical symbol for Mercury is Hg . Much less mercury is now used in consumer batteries and fluorescent lighting, but it has not been entirely eliminated. The total electrical charge of the nucleus is therefore +Ze, where e (elementary ch… Mercury: chemical properties Like cadmium, zinc and lead, mercury is a naturally occurring element known as a "heavy metal" and can be toxic to living organisms. The same amount has existed on the planet since the earth was formed. World production of mercury is around 8.000 tonnes per year. Although its form and availability to living organisms may change over time, mercury persists in the environment. Mercury has a number of effects on humans, that can all of them be simplified into the following main effects: - Disruption of the nervous system - Damage to brain functions - DNA damage and chromosomal damage - Allergic reactions, resulting in skin rashes, tiredness and headaches - Negative reproductive effects, such as sperm damage, birth defects and miscarriages Damaged brain functions can cause degradation of learning abilities, personality changes, tremors, vision changes, deafness, muscle incoordination and memory loss. Ground mixtures of sodium carbide and mercury can react vigorously [Mellor 5:848. Its Its ease in amalgamating with gold is used in the recovery of gold from its ores. It has a relatively high electrical conductivity … Acidic surface waters can contain significant amounts of mercury. The element also combines with other metals such as tin, copper, gold and silver to form mercury alloys known as amalgams. It is insoluble in acids and alkalis. Mercury (II) or mercuric compounds predominate. Mercury has a … Safety Data Sheet Mercury (Metallic) SDS Revision Date: 05/01/2015 Page 3 of 9 4. Method 3500-Hg B Cold Vapour Atomic Absorption Method [6]. Mercury is a silvery-white shiny heavy liquid with stable chemical properties. Mercury is a transition metal, where one of the elements found between Group 2 (IIA) and 13 (IIIA) on the periodic table. Never give anything by mouth to an unconscious person. Mercury is the only common metal which is liquid at ordinary temperatures. Elemental mercury (Hg0) has no electric charge. Mercury Chemical Properties. Once mercury has reached surface waters or soils microrganisms can convert it to methyl mercury, a substance that can be absorbed quickly by most organisms and is known to cause nerve damage. The chemical symbol for Mercury is Hg. Description of first aid measures General In all cases of doubt, or when symptoms persist, seek medical attention. The effects that mercury has on animals are kidneys damage, stomach disruption, damage to intestines, reproductive failure and DNA alteration. 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. However, when a thermometer will break a significantly high exposure to mercury through breathing will occur for a short period of time while it vaporizes. Metallic mercury is a shiny, silver-white, odorless liquid. Vermilion, a red pigment, is mercuric sulphide; another crystalline form of the sulphide (also used as a pigment) is black. It is extremely volatile, meaning it can easily be converted into gaseous form. Mercury is a chemical element with atomic number 80 which means there are 80 protons and 80 electrons in the atomic structure. Mercury and Platinum chemical properties are one of the most important characteristics It can be changed into a gas ("boiled") at 365.6°C (690.1°F). The liquid is highly mobile and droplets combine easily due to low viscosity. Mercury reacts with atmospheric oxygen, in the presence of moisture, to form a gray oxide. Industry uses mercury metal as a liquid electrode in the manufacture of chlorine and sodium hydroxide by electrolysis of brine. That makes it one of the 20 least common elements. Occurrence in nature. Some forms of human activity release mercury directly into soil or water, for instance the application of agricultural fertilizers and industrial wastewater disposal. 1 decade ago. Release of mercury from natural sources has remained fairly the same over the years. It is a rather poor conductor of heat if compared with other metals but it is a fair conductor of electricity. 41:1048. 1963]. As a chemical element, mercury cannot be created or destroyed. Mercury, Silver Liquid Mercury, Red Mercury, Metallic Mercury CAS NO.7439-97-6: 7439-97-6: Hebei yanxi chemical co.,LTD. Like all substances it has its own unique set of physical and chemical properties. Because of its high density it is used in barometers and manometers. It is one of the few metals which is liquid at room temperature. The structure, chemical formula, and physical and chemical properties of some Hg-containing compounds are shown in Table 2-1. Anonymous. Methyl azide in the presence of mercury is potentially explosive [Can. Chemical properties valence states: elementar Hg 0, mercurous Hg +1, mercuric Hg +2 most stable form: elementar mercury thermally unstable both forms Hg +1, Hg +2, decompose to elemental mercury ionic forms: Hg 2 2+, Hg 2+ inorganic mercury mainly in a form of salts, mostly week soluble in water Mercury is a very rare element in the Earth's crust. Mercury is sometimes called quicksilver. 0 0. Bromine is a non-metal. Structure, properties, spectra, suppliers and links for: Mercury(II) chloride, 7487-94-7, 51312-24-4, Mercuric chloride, HgCl2. Fish are organisms that absorb great amounts of methyl mercury from surface waters every day. 1946-47]. As the water rises it leaves deposits of sulfur, forming a red-colored mineral called cinnabar, or mercury sulfide. As a chemical element, It cannot be created or destroyed. The element's atomic mass is 200.59 grams per mole and its specific gravity is 13.5 times that of water. Because iron is an exception to this rule, iron flasks have been traditionally used to trade mercury. Properties and Uses of Mercury Mercury is an Element Imagine, long ago, hot lava flowing down a volcano in Italy. 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. Mercury has a relatively high vapour pressure and the highest volatility of any metal, vapourizing to become a colourless, odourless gas. Mercury Mercury is a chemical element with symbol Hg and atomic number 80. "Ammonia". Mercury is not a property; it is a substance. Elemental mercury is liberated by hydrochloric acid and stannous chloride. Mercury is still used in some electrical gear, such as switches and rectifiers, which need to be reliable, and for industrial catalysis. The Physical and Chemical Properties are the characteristics of a substance, like Mercury, which distinguishes it from any other substance. Hg2+ is also found in organic (carbon based) substances like dimethylmercury (Me2Hg), which is far more toxic than inorganic forms of mercury and bioaccumulates in the tissues of living organisms. Mercury is not commonly found in plant products, but it can enter human bodies through vegetables and other crops, when sprays that contain mercury are applied in agriculture. You will not receive a reply. Mercury occurs uncombined in nature to a limited extent. (Eggeman, Tim.
