The chemical element mercury has the atomic number 80 and the symbol Hg. It was once known as hydrargyrum and goes by the moniker quicksilver. The only other metallic element that is known to be liquid at ordinary temperature and pressure is the halogen bromine, while metals like caesium, gallium, and rubidium dissolve just above ambient temperature. Mercury is a heavy, silvery d-block element. Mercury (Hg), often known as quicksilver, is a chemical element that belongs to Periodic Table Group 12 (also known as Zinc Group IIb).

The density of mercury has been calculated using the Beattie formula based on the aforementioned mean value of density at 20oC. In addition to thermometry, the primary standard barometer and the volume of small capacity measures are both determined using mercury as a reference standard. The density values have been determined in steps of 0.1oC throughout the desired temperature range, which in either case is 0-41oC. Mercury’s density is based on an atmospheric pressure of 101325 Pa.
Mercury exists in seven stable isotopes, with 202Hg being the most prevalent (29.86%). The radioactive isotopes 194Hg, with a half-life of 444 years, and 203Hg, with a half-life of 46.612 days, have the longest half-lives. The majority of the radioisotopes that are still in existence have half-lives of under a day. The most often investigated NMR-active nuclei are 199Hg and 201Hg, which have spins of 12 and 32, respectively. The trace isotope 196Hg and the more abundant 198Hg are two stable mercury isotopes that may be of importance for the synthesis of valuable metals.
Mercury has an average crustal abundance by mass of just 0.08 parts per million, making it a very uncommon element in the Earth’s crust (ppm). Mercury ores can be incredibly concentrated given the element’s abundance in regular rock since it geochemically does not blend with those elements that make up the majority of the crustal mass. Even the leanest concentrated deposits are at least 0.1% mercury, whereas the richest mercury ores can contain up to 2.5% mercury by mass (12,000 times average crustal abundance). It can be discovered as a native metal (rare) or in minerals such as cinnabar (HgS), metacinnabar, sphalerite, corderoite, livingstonite, and others. Hot springs and other volcanic zones are frequent locations of mercury ores.
Mercury is a chemical element that occurs naturally. Mercury is found in rock in the earth’s crust and also in deposits of coal. Mercury is named ‘Hg’ in the periodic table with the atomic number 80. It is quicksilver, heavy, silvery-white liquid metal. Mercury is a transition metal. It can neither be created nor destroyed as a chemical element. The density of mercury is 13.6 g.cm-3 at 20°C. Mercury has many useful applications and is an element with properties hazardous to the environment.
Mercury is a chemical element with the symbol Hg and atomic number 80. It is also known as quicksilver and was formerly named hydrargyrum. Hydrargyrum is from the Greek word hydor meaning water and argyros meaning silver. It is a heavy silvery d-block element, mercury is the only metallic element that is known to be liquid at standard conditions for temperature and pressure.
Mercury is generally used in thermometers, barometers, manometers, mercury switches, mercury relays, fluorescent lamps, etc. Mercury is used in scientific research and amalgam for dental restoration.
The density of mercury at 20 degrees Celcius is 13545.848 kg/M3. Mercury is used as a reference stand for determining the volume of small capacity measures and to maintain the primary standard barometer. In either case, the temperature range of interest is 0-41°C, therefore the density has been calculated in steps of 0.1°C. The value for the density of mercury refers to an ambient pressure of 101325 Pa. Mercury has been introduced to mankind for thousands of years. This metal is made from the most important ore called Cinnabar. The Cinnabar release mercury as a vapor when heated, later these vapors are cooled and captured as liquid mercury.
Mercury metal can be frozen and changed into solid at a temperature of -38.85°C and it can be transformed into a gas when boiled at 365.6°C. The major physical properties of Mercury are that it has very high surface tension and very good conductor of electricity.
What is Surface tension? Surface tension is a property of a liquid that makes it act like they are covered with skin. While being a good conductor of electricity, this property is used in mercury switches to turn lights on and off.
Mercury is a good conductor of electricity. In several functional products, this property is used. One such gadget is a mercury switch.
Mercury is a heavy, silver-white metal that is liquid at room temperature.
Mercury doesn’t react with most acids, including dilute sulfuric acid. Mercury reacts with atmospheric hydrogen sulfide. Mercury reacts with solid sulfur flakes, which are used in mercury spill kits to absorb mercury.
Mercury is dissolved in many metals such as gold and silver to form amalgams.
Mercury readily combines with aluminum to form mercury to form a mercury-aluminum amalgam when the two pure metals come into contact. Since the amalgam destroys the aluminum oxide layer which protects metallic aluminum from oxidizing in-depth, even small amounts of mercury can seriously corrode aluminum. Mercury is not allowed aboard an aircraft under most circumstances because of the risk of it forming an amalgam with exposed aluminum parts in the aircraft.
Mercury has several applications, as it has high density. Mercury is used in thermometers, barometers, sphygmomanometers, float valves, mercury switches, mercury relays, fluorescent lamps, and other devices. The uses of Mercury are listed below.
The chemical element mercury has the atomic number 80 and the symbol and formula are Hg. It was once known as hydrargyrum in Greek, and it also goes by the term quicksilver.
Historically known as quicksilver, elemental or metallic mercury is a gleaming, silver-white metal that is liquid at ambient temperature. Older thermometers, fluorescent lamps, and some electrical switches all use it.
When Mercury is released from rock and ends up in the atmosphere and water Mercury becomes a problem for the environment. These emissions can happen naturally. Mercury can be released both by volcanoes and forest fires.
Human activities are responsible for much of the mercury that is released into the environment. The burning of coal, oil, and wood as fuel can cause mercury to become airborne, as can burning wastes that contain mercury.
This airborne mercury can also fall to the ground in the form of raindrops, dust, or simply due to gravity. The amount of mercury deposited in an area depends on how much mercury is released from local, regional, national, and international sources.
Ans. Mercury is a harmful or poisonous metal that can be harmful when exposed to people. If mercury is swallowed it will absorb very little in the body.
Ans. Mercury is rarely present as a pure, liquid metal in nature. Mercury is extracted as Mercury sulfide from Cinnabar ore. Cinnabar deposits have been the source of ores for the commercial exploitation of metallic mercury.
Ans. Mercury is a shiny silver metal that contains highly toxic constituents. Mercury is highly harmful to humans with the symbol Hg.
Ans. Mercury is used to produce thermometers, barometers, sphygmomanometers, and other scientific tools.
Ans. The ancient Chinese, Egyptians, and Hindus understood the properties of Mercury and discovered them in Egyptian tombs dating back to around 1500 BC
