Mercury (element)

Mercury has a relatively high vapour pressure and the highest volatility of any metal, vapourizing to become a colourless, odourless gas. The metal is a fair conductor of electricity, but a poor conductor of heat. Mercury's atomic number is In nature, mercury has 3 possible conditions of electrical charge, or valence states. Apr 01,  · At room temperature, mercury is a thick, silvery liquid with a very high density and low heat conductivity. It has a relatively high electrical conductivity .

Mercury, or 'quicksilver' as it is otherwise known, is a dense, toxic metal element that exists in liquid form at room temperature. Produced and studied for millennia, mercury's use has steadily declined since the s as a result of greater attention to the negative health impacts that it has on humans and the wat.

At room temperature, mercury is a thick, silvery liquid with a very high density and low heat conductivity. It has a relatively high electrical conductivity and readily forms amalgams alloys with gold and silver. One of mercury's most valued characteristics is its ability to uniformly expand and contract over its entire liquid range, in response to changes in pressure and temperature.

Mercury is also highly toxic to both humans and the environment, which has resulted in drastic reductions to its production and use over the what are the properties of mercury several decades.

Likely due to its unique properties, mercury was used, studied and prized by numerous civilizations, including the ancient Greeks, What are the properties of mercury, Chinese and Mayans. For centuries, people believed that mercury possessed special healing properties and, consequently, used it as a diuretic and painkiller, as well as in medicines to treat various ailments from depression to syphilis.

It has been used in cosmetics and as a decorative material. Alchemists in the Middle Ages were particularly interested in mercury's ability to extract gold from ore. Early on, it became oof that the mysterious liquid metal was toxic to humans because of the high instance of insanity and death in mercury mines.

It, however, did not prevent experimentation. The use of mercury nitrate to convert fur to felt, often employed by 18th and 19th-century hat makers, resulted properrties the expression 'mad as a hatter.

What is meant by in lieu of andBartolome de Medina developed the patio process for extracting silver from ores using mercury.

The patio process relies on mercury's ability to amalgam with silver. Supported by large mercury mines in Almaden, Spain, and Huancavelica, Peru, the patio process was critical to the rapid expansion of Spanish silver production during the 17th and 18th centuries. Later, during the California gold rush, variations of the patio process were used to extract gold. By the second half of the 20th century, increasing amounts of research began to prove a correlation between chemical waste run-off and methyl-mercury content in seafood.

Attention was put on the metal's health effects on humans. In recent years, the United States and the European Union have put in place strict regulations on the production, use, and disposal of mercury. Mercury is a very rare metal and is most often found in the ores cinnabar and livingstonite. It is produced as a primary product and as a by-product of gold, zincand copper.

Mercury can be produced from cinnabar, a sulfide ore HgSby burning off the sulfide content in a rotary kiln or multiple hearth furnaces. Oxygen is pumped into the furnace, which combines with the sulfur, releasing sulfur dioxide and creating a mercury vapor that can be collected and cooled for virtual families 2 how to get triplets refinement as a pure metal.

By passing the mercury vapor through a water-cooled ate, the mercury, which has a high boiling point, is the first to condense into its liquid metal form and collected. Mercury can also be leached from ores using sodium hydroxide and sodium sulfide. Recovery of the mercury is done by precipitation using aluminum or electrolysis. Through distillation, mercury can be purified to greater than Commercial-grade, Production of, and demand for, mercury has steadily declined since its peak in the early s.

The primary application for mercury metal in North America and Europe is in cathode cells, which are used for the production of caustic soda. In China, the polyvinylchloride PVC industry is the largest consumer of mercury. Production of coal-based PVC, like that produced ae China, requires the use of mercury as a catalyst. Perhaps the how to remove cigarette tar from teeth well-known use of mercury is in thermometers and barometers.

However, this use is also steadily declining. Galinstan an alloy of gallium, indium, and tin has mostly replaced mercury in thermometers because of the alloy's lower toxicity. Mercury's ability to amalgamate with precious metals, aiding in their recovery, has resulted in its continued use in many developing countries with alluvial gold mines. While contentious, the use of mercury in dental how to clean up glass shards continues and, despite the development of alternatives, is still a major industry for the metal.

One of the few uses for mercury that has been growing in recent years is in compact fluorescent light bulbs CFLs. Government programs encouraging the elimination of less energy efficient incandescent bulbs have supported demand for CFLs, pdoperties require gaseous mercury. Mercury compounds are also used in batteries, drugs, industrial chemicals, paints and mercury-fulminate, a detonator for explosives.

Recent efforts propertirs been made by the US and EU to propertles the trade of mercury. Exports of mercury from all EU member states were banned as of March Norway has what day of the week is christmas 2009 put in place wht ban on the production, import, and export of mercury.

The Physical properties of Mercury are the characteristics that can be observed without changing the substance into another substance. Physical properties are usually those that can be observed using our senses such as color, luster, freezing point, boiling point, melting point, density, hardness and odor.

What are the Properties of Mercury? Definition of Mercury What is the definition of Mercury? It is a silver white poisonous metallic element with a mirror-like appearance. It is a liquid at room temperature and used in thermometers, barometers, vapor lamps, and batteries and in chemical pesticides. The Physical and Chemical Properties are the characteristics of a substance, like Mercury, which distinguishes it from any other substance. Most common substances, like Mercury, exist as States of Matter as solids, liquids, gases and plasma.

Refer to the article on Mercury Element for additional information and facts about this substance. What are the Physical Properties of Mercury? The Physical properties of Mercury are the characteristics that can be observed without changing the substance into another substance.

Physical properties are usually those that can be observed using our senses such as color, luster, freezing point, boiling point, melting point, density, hardness and odor. The Physical Properties of Mercury are as follows:. When mercury is spilled, it breaks up into tiny beads which often become lodged in cracks Density High Density Mercury Properties - What are the Chemical Properties of Mercury? What are the Chemical Properties of Mercury?

They are the characteristics that determine how it will react with other substances or change from one substance to another.

The better we know the nature of the substance the better we are able to understand it. Chemical properties are only observable during a chemical reaction. Reactions to substances may be brought about by changes brought about by burning, rusting, heating, exploding, tarnishing etc. The Chemical Properties of Mercury are as follows:. Mercury Properties. When mercury is spilled, it breaks up into tiny beads which often become lodged in cracks Density High Density. Chemical Formula Hg Toxicity Highly toxic Reactivity with acids Reacts with some acids when they are hot, but does not react with most cold acids Oxidation Does not readily react with oxygen in the air Compounds Many of mercury's compounds are pigments, pesticides and medicines.
