mercury atomic mass

Chlorine is produced from sodium chloride (common salt, NaCl) using electrolysis to separate the metallic sodium from the chlorine gas. Hg (Mercury) Atomic Number 80 Learn more about the atomic number. Mercury Atomic Mass. It is used in some thermometers, especially ones which are used to measure high temperatures. [125] The convention was signed on 10 October 2013. This study found mercury concentrations significantly elevated over outdoor concentrations, at a range of 0.0065 – 0.523 μg/m3. Most of the remaining radioisotopes have half-lives that are less than a day. Mercury is the only metal for which the alchemical planetary name became the common name. Number of Neutrons:121. Although that can be considered a natural level of exposure, regional or global sources have significant effects. [9] Upon freezing, the volume of mercury decreases by 3.59% and its density changes from 13.69 g/cm3 when liquid to 14.184 g/cm3 when solid. Water run-off from such sites is a recognized source of ecological damage. Another mercury compound, merbromin (Mercurochrome), is a topical antiseptic used for minor cuts and scrapes that is still in use in some countries. Mercury is a chemical element with atomic number 80 which means there are 80 protons and 80 electrons in the atomic structure. [130] However newer data published in 2015 showed that after introduction of the stricter controls mercury declined sharply, indicating that the Clean Air Act had its intended impact. Environmental dangers have been a concern, particularly in the southern cities of Foshan and Guangzhou, and in Guizhou province in the southwest. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element. Discovered By: Known to the ancients. [133], In the European Union, the directive on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment (see RoHS) bans mercury from certain electrical and electronic products, and limits the amount of mercury in other products to less than 1000 ppm. Period and Group: Period : 6 Group: 12. Mercury is used in thermometers, barometers, manometers, sphygmomanometers, float valves, mercury switches, mercury relays, fluorescent lamps and other devices, though concerns about the element's toxicity have led to mercury thermometers and sphygmomanometers being largely phased out in clinical environments in favor of alternatives such as alcohol- or galinstan-filled glass thermometers and thermistor- or infrared-based electronic instruments. For 12C the atomic mass is exactly 12u, since the atomic mass unit is defined from it. Gaseous mercury is used in mercury-vapor lamps and some "neon sign" type advertising signs and fluorescent lamps. Species of fish that are high on the food chain, such as shark, swordfish, king mackerel, bluefin tuna, albacore tuna, and tilefish contain higher concentrations of mercury than others. "[139], Products containing mercury were banned in Sweden in 2009.[140][141]. They form tetrahedral complexes with other ligands but the halides adopt linear coordination geometry, somewhat like Ag+ does. The equation for this extraction is. [120] Acute exposure to mercury vapor has been shown to result in profound central nervous system effects, including psychotic reactions characterized by delirium, hallucinations, and suicidal tendency. Mercury can be absorbed through the skin and mucous membranes and mercury vapors can be inhaled, so containers of mercury are securely sealed to avoid spills and evaporation. The Standard English unit is pounds mass per cubic foot (lbm/ft3). These are subsequently inhaled during tobacco smoking. Commercial calibration lamps are sold for this purpose; reflecting a fluorescent ceiling light into a spectrometer is a common calibration practice. Sources, facts, uses, scarcity (SRI), podcasts, alchemical symbols, videos and images. Compared to other metals, it is a poor conductor of heat, but a fair conductor of electricity. Name:Mercury. ), Basic Mercury Subsulphate; Turpeth Mineral, Quantities of liquid mercury ranging from 90 to 600 grams (3.2 to 21.2 oz) have been recovered from elite, As an electrically conductive liquid, it was used in, Owing to its acoustic properties, mercury was used as the propagation medium in, Mercury was used for preserving wood, developing. mercury cadmium telluride and mercury zinc telluride being semiconductors useful as infrared detector materials.[42]. The purest of these was gold, and mercury was called for in attempts at the transmutation of base (or impure) metals into gold, which was the goal of many alchemists. For other isotopes, the isotopic mass usually differs and is usually within 0.1 u of the mass number. [94], Natural sources, such as volcanoes, are responsible for approximately half of atmospheric mercury emissions. [126], In the United States, the Environmental Protection Agency is charged with regulating and managing mercury contamination. [107] While mercury is a constituent of tobacco smoke,[108] studies have largely failed to discover a significant correlation between smoking and Hg uptake by humans compared to sources such as occupational exposure, fish consumption, and amalgam tooth fillings. Mercury is the only metallic element that is a liquid at room temperature. Mercury has been used in manufacturing, as well as in dental and medical equipment, fertilizers, and pesticides. [105][106], The tobacco plant readily absorbs and accumulates heavy metals such as mercury from the surrounding soil into its leaves. The atomic mass is the mass of an atom. Mercury(II) salts are a rare example of simple metal complexes that react directly with aromatic rings. Thousands of prisoners were used by the Luo Xi mining company to establish new tunnels. Mercury: Symbol: Hg: Atomic Number: 80: Atomic Mass: 200.59 atomic mass units: Number of Protons: 80: Number of Neutrons: 121: Number of Electrons: 80: Melting Point-38.87° C: Boiling Point: 356.58° C: Density: 13.456 grams per cubic centimeter: Normal Phase: Liquid: Family: Transitions Metals: Period Number: 6: Cost: Unavailable Atomic mass of Mercury is 200.59 u. The richest mercury ores contain up to 2.5% mercury by mass, and even the leanest concentrated deposits are at least 0.1% mercury (12,000 times average crustal abundance). 11% from gold production.

Mercury occurs in deposits throughout the world mostly as cinnabar (mercuric sulfide).
