Refer to the article on Mercury Element for additional information and facts about this substance. It can be found in metal form, as mercury salts or as organic mercury compounds. Mercury fulminate, Hg(CNO)2, is used as a detonator. Mercury compounds have many uses. Fortunately, mercury does not form amalgam with iron, which allows for the element to be shipped in standard iron flasks containing 76 pounds, or 34.5 kilograms, of liquid mercury. Mercury is a transition metal, where one of the elements found between Group 2 (IIA) and 13 (IIIA) on the periodic table. Industry uses mercury metal as a liquid electrode in the manufacture of chlorine and sodium hydroxide by electrolysis of brine. Mercuric sulfide (HgS) is reddish-orange in color. Mercury is still used in some electrical gear, such as switches and rectifiers, which need to be reliable, and for industrial catalysis. Jump to main content Jump to site nav Home 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). Vermilion, a red pigment, is mercuric sulphide; another crystalline form of the sulphide (also used as a pigment) is black. Safety Data Sheet Mercury (Metallic) SDS Revision Date: 05/01/2015 Page 3 of 9 4. Mercury concentrations in fish usually greatly exceed the concentrations in the water they live in. Mercury is a chemical element with the symbol Hg and atomic number 80. The abundance of mercury in the Earth's crust is estimated to be about 0.5 parts per million.

Mercury is a very rare element in the Earth's crust. 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. (Eggeman, Tim. 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). It rarely occurs free in nature and is found mainly in cinnabar ore (HgS) in Spain, Russia, Italy, China and Slovenia. Properties and Uses of Mercury Mercury is an Element Imagine, long ago, hot lava flowing down a volcano in Italy. Mercury Mercury is a chemical element with symbol Hg and atomic number 80. It is commonly known as quicksilver and was formerly named hydrargyrum. 1963]. Fish are organisms that absorb great amounts of methyl mercury from surface waters every day. It accounts for only about 0.08 parts per million … Mercury is moderately active. The element's atomic mass is 200.59 grams per mole and its specific gravity is 13.5 times that of water. Mercury Chemical Properties. Mercury has a … In nature, mercury has 3 possible conditions of electrical charge, or valence states. Mercury is a chemical element with the symbol Hg and atomic number 80. Mercury is the only common metal which is liquid at ordinary temperatures. Deep within the cooling layers of rock, water rises on its way toward the surface. 41:1048. Structure, properties, spectra, suppliers and links for: Mercury(II) chloride, 7487-94-7, 51312-24-4, Mercuric chloride, HgCl2. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. Mercury is a chemical element and the only common metal which is liquid at ordinary temperatures. 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). It reacts with some acids when they are hot, but not with most cold acids. As the water rises it leaves deposits of sulfur, forming a red-colored mineral called cinnabar, or mercury sulfide. Mercuric chloride (corrosive sublimate, HgCl2) is used as an insecticide, in rat poison, and as a disinfectant. The nucleus is composed of protons and neutrons. The element also combines with other metals such as tin, copper, gold and silver to form mercury alloys known as amalgams. It has no RADIOACTIVITY but heavy to disintegrate hence harmful. Mercury is sometimes called quicksilver. Mercury is a silvery-white shiny heavy liquid with stable chemical properties. 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. The effects that mercury has on animals are kidneys damage, stomach disruption, damage to intestines, reproductive failure and DNA alteration. Mercury is sometimes called quicksilver. Because iron is an exception to this rule, iron flasks have been traditionally used to trade mercury. As a chemical element, It cannot be created or destroyed. As a consequence, methyl mercury can accumulate in fish and in the food chains that they are part of. It is extensively used in thermometers, thanks to its high rate of thermal expansion that is fairly constant over a wide temperature range. Occurrence in nature. 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. Ground mixtures of sodium carbide and mercury can react vigorously [Mellor 5:848. The same amount has existed on the planet since the earth was f… Some forms of human activity release mercury directly into soil or water, for instance the application of agricultural fertilizers and industrial wastewater disposal. Calomel (mercurous chloride, Hg2Cl2) is used as a standard in electrochemical measurements and in medicine as a purgative. The metal is a fair conductor of electricity, but a poor conductor of heat. It alloys easily with many metals, such as gold, silver, and tin. Mercury reacts with chlorine and sulfur, to form compounds such as mercuric chloride, mercurous chloride, mercuric sulfide, etc. The element's atomic mass is 200.59 grams per mole and its specific gravity is 13.5 times that of water. Hazard Summary Mercury exists in three forms: elemental mercury, inorganic mercury compounds (primarily mercuric chloride), and organic mercury compounds (primarily methyl mercury). 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). Principal compounds The compounds of mercury are either of +1 or +2 oxidation state. 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. Chemical properties. Droplets of liquid mercury are shiny and silver-white with a high surface tension, appearing rounded when on flat surfaces. Mercury enters the environment as a result of normal breakdown of minerals in rocks and soil through exposure to wind and water. Acidic surface waters can contain significant amounts of mercury. It is a rather poor conductor of heat if compared with other metals but it is a fair conductor of electricity. Although its form and availability to living organisms may change over time, mercury persists in the environment. Chemical properties of Mercury: Mercury (chemical symbol Hg) is an amazing element. These alloys are called amalgams. Mercury evaporates at room temperature, and most of the mercury vapor and mercury compounds are highly toxic (chronic). Mercury has a relatively high vapour pressure and the highest volatility of any metal, vapourizing to become a colourless, odourless gas. Its Its ease in amalgamating with gold is used in the recovery of gold from its ores. Mercury (II) or mercuric compounds predominate. Chromosomal damage is known to cause mongolism. It is commonly known as quicksilver and is heavy, silvery-white liquid metal. Mercury is commonly known as quicksilver and was formerly named hydrargyrum. It can be changed into a gas ("boiled") at 365.6°C (690.1°F). That makes it one of the 20 least common elements. When heated it becomes a colorless, odorless gas. Mercuric sulphate is used as a catalyst in organic chemistry. Mercury is not naturally found in foodstuffs, but it may turn up in food as it can be spread within food chains by smaller organisms that are consumed by humans, for instance through fish. This can cause harmful effects, such as nerve, brain and kidney damage, lung irritation, eye irritation, skin rashes, vomiting and diarrhoea. The mercury in these devices is trapped and usually does not cause any health problems. It is one of the few metals which is liquid at room temperature. Like all substances it has its own unique set of physical and chemical properties. All mercury that is released in the environment will eventually end up in soils or surface waters. As a chemical element, mercury cannot be created or destroyed. Given below are the facts on the chemical properties of mercury. The chemical symbol for Mercury is Hg. At room temperature, mercury is a thick, silvery liquid with a very high density and low heat conductivity. Metallic mercury is used in a variety of household products, such as barometers, thermometers and fluorescent light bulbs. Like cadmium, zinc and lead, mercury is a naturally occurring element known as a "heavy metal" and can be toxic to living organisms. Mercuric oxide is used in skin ointments. Since mercury can be adsorbed easily onto small particles of matter, some scientists use the notation Hg(p) to represent elemental mercury attached onto or absorbed into a particle. Ammonia forms explosive compounds with gold, mercury, or silver. All forms of mercury are quite toxic, and each form exhibits different health effects. The Physical and Chemical Properties are the characteristics of a substance, like Mercury, which distinguishes it from any other substance. The mercuric cation is more stable and is generally associated with inorganic molecules, such as sulfur (in the mineral cinnabar), chlorine (mercuric chloride), oxygen and hydroxyl ions. When the pH values are between five and seven, the mercury concentrations in the water will increase due to mobilisation of mercury in the ground. 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 Never give anything by mouth to an unconscious person. 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. Mercury is not a property; it is a substance. Mercury occurs uncombined in nature to a limited extent. The liquid is highly mobile and droplets combine easily due to low viscosity. Mercury (Hg) is a naturally occurring metal. 0 0. Source(s): Mercury from soils can accumulate in mushrooms. It is a heavy, silvery-white liquid metal. Mercury metal has many uses. Inquiry: Mercury -- CHemwill Mercury is also found in two positively charged, or cationic, states, Hg2+ (mercuric) and Hg1+(mercurous). 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. "Ammonia". Mercury is the only common metal which is liquid at ordinary temperatures. Elemental mercury (Hg0) has no electric charge. It is extremely volatile, meaning it can easily be converted into gaseous form. Methyl azide in the presence of mercury is potentially explosive [Can. Much less mercury is now used in consumer batteries and fluorescent lighting, but it has not been entirely eliminated. 1946-47]. Mercury and Platinum chemical properties are one of the most important characteristics Most common substances, like Mercury, exist as States of Matter as solids, liquids, gases and plasma.

It does not react with oxygen in the air very readily. The structure, chemical formula, and physical and chemical properties of some Hg-containing compounds are shown in Table 2-1. Release of mercury from natural sources has remained fairly the same over the years. Mercury reacts with atmospheric oxygen, in the presence of moisture, to form a gray oxide. The same amount has existed on the planet since the earth was formed. Description of first aid measures General In all cases of doubt, or when symptoms persist, seek medical attention. 1 decade ago. Mercury is a silvery-white, shiny metal, which is liquid at room temperature. Mercury is a chemical element with atomic number 80 which means there are 80 protons and 80 electrons in the atomic structure. 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. Vapours are purged into a cold vapour cell on the atomic absorption spectrophotometer and quantified using a wavelength of 257.3 nm. In fact, there is only one other liquid element, bromine. Mercury dissolves to form amalgams with gold, zinc and many metals. Mineable reserves are around 600.000 tonnes. Physical properties Mercury is the only liquid metal. You will not receive a reply.
