Mercury is a chemical element with symbol Hg and atomic number 80. It is commonly known as quicksilver and was formerly named hydrargyrum.
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 bromine, though metals such as caesium, gallium, and rubidium melt just above room temperature. Mercury occurs in deposits throughout the world mostly as cinnabar (mercuric sulfide).
The red pigment vermilion, a pure form of mercuric sulfide, is mostly obtained by reaction of mercury (produced by reduction from cinnabar) with sulfur. Mercury poisoning can result from exposure to water-soluble forms of mercury (such as mercuric chloride or methylmercury), inhalation of mercury vapor, or eating seafood contaminated with mercury.
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 favour of alternatives such as alcohol- or galinstan-filled glass thermometers and thermistor- or infrared-based electronic instruments.
Likewise, mechanical pressure gauges and electronic strain gauge sensors have replaced mercury sphygmomanometers. Mercury remains in use in scientific research applications and in amalgam material for dental restoration in some locales. It is used in 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.

Forest & Ray Holborn Dentist address: 8F Gilbert Place, London, WC1A 2JD. About Camden: Lincoln's Inn Fields is a neighbourhood in the extreme south of the borough that is only 500 metres from the Thames. The northern part of the borough is home to Kentish Town, Hampstead, and Hampstead Heath, which are less populous districts. Numerous parks and open areas may be found in this London Borough, as well as Forest & Ray Dentist Camden. City of Westminster (near Soho, London) and the City of London are the next-door boroughs, followed by Brent to the west of what was once Roman Watling Street (now the A5 Road), Barnet and Haringey to the north, and Islington to the east. It encompasses all or a portion of the following postcode areas: N1, N6, N7, N19, NW1, NW2, NW3, NW5, NW6, NW8, EC1, WC1, WC2, W1, and W9.
The borough of Camden also includes Bloomsbury, known for its garden squares. To the west, the fashionable district of Marylebone is rich in shops and restaurants, while the prestigious Mayfair extends slightly into Camden. Covent Garden, famed for its entertainment and market, adds to Camden's vibrancy. Bordering the east of the borough are Clerkenwell and Farringdon, hubs for the design industry and renowned for their mix of old and new architecture. Although Lambeth and South Bank are located south of the Thames and not within Camden, they contribute to the broader cultural scene that Camden residents can easily access. To the east of Camden, beyond Islington, lies the diverse and bustling borough of Hackney, which provides a distinct cultural blend of its own.
