Mercury :: essays research papers

quicksilver atomic number 80 is a metallic element that is a transparent at room temperature, itis one of the transition elements. quicksilvers atomic number is 80. It issuperconductive when cooled to in spite of appearance a few degrees of absolute zero. Mercurywas once known as liquid silver or quicksilver which was studied by theal pill pushers. Mercury was first distinguished as an element by the French chemistAntoine Laurent Lavoisier in his experiment on the composition of air. At roomtemperature atomic number 80 is a shining, moving liquid that has a silvery-white color,and slightly volatile. Mercury stay a liquid over a wide temperature range.Mercury is a solid when given a pressure of 7640 atmospheres (5.8 million torrs).It dissolves in nitrous or concentrated sulfuric acid but is resistant toalkalies. Mercury melts at -39C, boils at about 357C,and has a gravity of 13.5.The atomic pack of mercury is 200.59. Mercury comes in its pure spend a penny orunite with silve r in small amounts. It is mostly found in the form of thesulfide.Mercury has many hires and is a very important element. A study use ofmercury is in electrical equipment such as light lamps, and mercurybatteries. Mercury is used in thermometers because the change in quite a little foreach degree of rise or fall in temperature is the same. The use of mercury inthe thermometer instead of alcohol was done by Gabriel Daniel Fahrenheit(postnominal) in 1714.It was also used in vacuum pumps, barometers, and electric rectifiers andswitches. Mercury is used in a mercury-vapor lamps which are used as a sourceof ultraviolet rays in homes and for sterilizing water. Mercury-vapor is alsoused instead of travel in the boilers of some turbine engines. Mercury issometimes used for amalgamation. Amalgamation is a metallurgical process thatutilizes mercury to dissolve silver or meretricious to form an amalgam. This processhas been largely supplanted by the cyanide process, in which property or silver is
