What is "ozone"

ozone \o"zone\ ([=o]"z[=o]n or [-o]*z[=o]n"), n. [Gr. 'o`zwn smelling, p. pr. of 'o`zein to smell. See Odor.] (Chem.) A colorless gaseous substance ( O3) obtained (as by the silent discharge of electricity in oxygen) as an allotropic form of oxygen, containing three atoms in the molecule. It is a strong oxidizer, and probably exists in the air, though by the ordinary tests it is liable to be confused with certain other substances, as hydrogen dioxide, or certain oxides of nitrogen. It derives its name from its peculiar odor, which resembles that of weak chlorine.

1840, from German Ozon, coined in 1840 by German chemist Christian Friedrich Schönbein (1799-1868) from Greek ozon, neuter present participle of ozein "to smell" (see odor). So called for its pungent odor.

n. 1 (context chemistry English) An allotrope of oxygen (''symbol'' O₃) having three atoms in the molecule instead of the usual two; it is a blue gas, generated from oxygen by electrical discharge. 2 (context from an erroneous former belief that seaweed contains and releases ozone English) fresh air, especially that breathed at the seaside and smelling of seaweed.

n. a colorless gas (O3) soluble in alkalis and cold water; a strong oxidizing agent; can be produced by electric discharge in oxygen or by the action of ultraviolet radiation on oxygen in the stratosphere (where it acts as a screen for ultraviolet radiation)

Ozone (systematically named 1λ,3λ-trioxidane and catena-trioxygen), or trioxygen, is an inorganic molecule with the chemical formula . It is a pale blue gas with a distinctively pungent smell. It is an allotrope of oxygen that is much less stable than the diatomic allotrope , breaking down in the lower atmosphere to normal dioxygen. Ozone is formed from dioxygen by the action of ultraviolet light and also atmospheric electrical discharges, and is present in low concentrations throughout the Earth's atmosphere (stratosphere). In total, ozone makes up only of the atmosphere.

Ozone's odour is sharp, reminiscent of chlorine, and detectable by many people at concentrations of as little as in air. Ozone's O formula was determined in 1865. The molecule was later proven to have a bent structure and to be diamagnetic. In standard conditions, ozone is a pale blue gas that condenses at progressively cryogenic temperatures to a dark blue liquid and finally a violet-black solid. Ozone's instability with regard to more common dioxygen is such that both concentrated gas and liquid ozone may decompose explosively at elevated temperatures or fast warming to the boiling point. It is therefore used commercially only in low concentrations.

Ozone is a powerful oxidant (far more so than dioxygen) and has many industrial and consumer applications related to oxidation. This same high oxidising potential, however, causes ozone to damage mucous and respiratory tissues in animals, and also tissues in plants, above concentrations of about . This makes ozone a potent respiratory hazard and pollutant near ground level. However, the ozone layer (a portion of the stratosphere with a bigger concentration of ozone, from two to eight ppm) is beneficial, preventing damaging ultraviolet light from reaching the Earth's surface, to the benefit of both plants and animals.

Ozone is an American magazine focused on the hip hop music of the Southern United States. It was founded in Orlando, Florida in 2002 by current editor by Julia Beverly. In 2006 the magazine relocated its headquarters to Atlanta.

The magazine provided early coverage of southern artists including Stat Quo, Pitbull, and T-Pain. It has also included articles on musicians from other parts of the U.S. Ozone, including New York rapper Saigon on the cover of the April 2006 issue and Chicago emcee Twista on the cover of its January 2006, and October 2007 issues.

The magazine has a small number of staff and contributors. In addition to publisher and editor-in-chief Julia Beverly, features editor Eric Perrin and music editor Randy Roper make frequent contributions. Other contributors include recording artist Killer Mike, Charlamagne, mixtape artist DJ Wally Sparks, Wendy Day (founder of Rap Coalition, and contributor to Murder Dog magazine), Rohit Loomba and DJ ADG.

Ozone is a molecule consisting of three oxygen atoms.
