what is mercury element

Methylmercury, a highly toxic organic compound, is the form of mercury people in the U.S. encounter most frequently. Its symbol on the periodic table is Hg, and its atomic number is 80. Mercury is also a neurotoxin. Mercury is an extremely rare element in the earth's crust, having an average crustal abundance by mass of only 0.08 parts per million. It is a metal, but remains in liquid form at room temperature. In its inorganic form, mercury occurs abundantly in the environment, primarily as the minerals cinnabar and metacinnabar, and as impurities in other minerals. The only other liquid element under standard conditions is. Mercury can be bound to other compounds as monovalent or divalent mercury (also expressed as Hg(I) and Hg(II) or Hg2+, respectivel… This silvery white metal has the atomic number 80 and is represented the chemical symbol ‘Hg’. Learn more about consumer products that contain mercury. Mercury is a type of toxic metal that comes in different forms within the environment. 1. Mercury (element) From Wikimedia Commons, the free media repository. Mercury can be rightly considered as one of the elements with most ancient existence, and its discovery dates back to around 1500 B.C [1]. This dense metal is atomic number 80 with element symbol Hg. Mercury that remains in the air for prolonged periods of time and travels across continents is said to be in the "global cycle.". (1), (2), (3) In the fourth century B.C. Depending on these factors, mercury in the atmosphere can be transported over a range of distances -- anywhere from a few feet from its source, to halfway around the globe -- before it is deposited in soil or water. Report: Children's Exposure to Elemental Mercury (Agency for Toxic Substances & Disease Registry) (2009). Mercury (Hg) is an element that occurs in the environment naturally as a result of human activity. A less common way people are exposed to mercury is breathing mercury vapor. Mercury is a silvery-white poisonous metallic element. Mercury is a naturally-occurring chemical element found in rock in the earth's crust, including in deposits of coal. However, some people are exposed to high levels of mercury, including acute exposure (exposure occurring over a short period of time, often less than a day). Mercury and most of its compounds are highly toxic. History at your fingertips Sign up here to see what happened On This Day, every day in your inbox! It is considered one of the "heavy metal" because of its atomic weight and can be found as number eighty on the periodic table of elements. Discovery and History. The 2014 National Emissions Inventory, version 2, Technical Support Document (July 2018)(414 pp, 10 MB, About PDF) also describes trends in mercury emissions since 1990 in Table 2-14 (see pages 2-28 - 2-29 of the PDF document) and in Figure  2-4 (see page 2-30 of the PDF document). Most of the isotope data on this site has been obtained from the National Nuclear Data Center.Please visit their site for more information.. Isotopes With A … Mercury is a naturally-occurring chemical element found in rock in the earth’s crust, that exists in three main forms: elemental (aka metallic) mercury, inorganic mercury compounds, and methylmercury and other organic compounds . Mercury, also called quicksilver, is a chemical element in the periodic table that has the symbol Hg and atomic number 80. The amount of mercury deposited in a given area depends on how much mercury is released from local, regional, national, and international sources. Element Mercury (Hg), Group 12, Atomic Number 80, d-block, Mass 200.592. If the mercury is not immediately contained or cleaned up, it can evaporate, becoming an invisible, odorless, toxic vapor. Mercury occurs naturally in the environment and exists in a large number of forms. Mercury is also sometimes called quicksilver or liquid silver. They have been chosen as highlights of a particular topic, but do not represent the full range of … People are exposed to mercury in three main ways: Burning coal and other fossil fuels that release mercury into the atmosphere … The burning of municipal and medical waste was once a major source of mercury emissions.
