BUY MERCURY POWDER Mercury is a chemical element with the symbol Hg and atomic number 80. A heavy,
silvery d-block element, mercury is the only metallic element that is liquid at standard conditions for temperature
and pressure; the only other element that is liquid under these conditions is the halogen bromine, though metals
such as caesium, gallium, and rubidium melt just above room temperature. Established in the year 2011,
Parshwamani Metals is a distinguished manufacturer, supplier and trader offering an enormous consignment of
Industrial Metal Tube, Beryllium Product, Shim Sheet, SS Round And Square Bar, Aluminium Products, Aluminum
Bronze Products etc. Besides these, we also provide products such as, Hollow Brass Tube, Brass Tube, Refrigeration
Copper Tube, Beryllium Copper Plates, Stainless Steel Shim Sheet, SS Square Bar, Aluminium Chequered Plates,
Nickel Aluminum Bronze etc. Mercury occurs in deposits throughout the world mostly as cinnabar (mercuric sulfide).
It remains in use in scientific research applications and in amalgam for dental restoration in some locales. It is also
used in fluorescent lighting.
Electricity passed through mercury vapor in a fluorescent lamp produces short-wave ultraviolet light, which then
causes the phosphor in the tube to fluoresce, making visible light. Mercury poisoning can result from exposure to
water-soluble forms of mercury (such as mercuric chloride or methylmercury), by inhalation of mercury vapor, or by ingesting any form of mercury.
Mercury does not react with most acids, such as dilute sulfuric acid, although oxidizing acids such as concentrated
sulfuric acid and nitric acid or aqua regia dissolve it to give sulfate, nitrate, and chloride. Like silver, mercury reacts
with atmospheric hydrogen sulfide. Mercury reacts with solid sulfur flakes, which are used in mercury spill kits to absorb mercury (spill kits also use activated carbon and powdered zinc).

A complete explanation of mercurys extreme volatility delves deep into the realm of quantum physics, but it can be
summarized as follows: mercury has a unique electron configuration where electrons fill up all the available 1s, 2s, 2p, 3s, 3p, 3d, 4s, 4p, 4d, 4f, 5s, 5p, 5d, and 6s subshells.
Because this configuration strongly resists removal of an electron, mercury behaves similarly to noble gases, which form weak bonds and hence melt at low temperatures.
The stability of the 6s shell is due to the presence of a filled 4f shell. An f shell poorly screens the nuclear charge that increases the attractive Coulomb interaction of the 6s shell and the nucleus (see lanthanide contraction).
The absence of a filled inner f shell is the reason for the somewhat higher melting temperature of cadmium and zinc, although both these metals still melt easily and, in addition, have unusually low boiling points.

Due to the health effects of mercury exposure, industrial and commercial uses are regulated in many countries.
The World Health Organization, OSHA, and NIOSH all treat mercury as an occupational hazard, and have
established specific occupational exposure limits. Environmental releases and disposal of mercury are regulated in the U.S. primarily by the United States Environmental Protection Agency.
It is used primarily for the manufacture of industrial chemicals or for electrical and electronic applications.
It is used in some thermometers, especially ones which are used to measure high temperatures. A still increasing amount is used as gaseous mercury in fluorescent lamps,
while most of the other applications are slowly phased out due to health and safety regulations and is in some applications replaced with less toxic but considerably more expensive Galinstan alloy.
