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)
An allotrope of oxygen (symbol O) having three atoms in the molecule instead of the usual two; it is a blue gas, generated from oxygen by electrical discharge; it is poisonous and highly reactive, but in the upper atmosphere it protects life on Earth from ultraviolet radiation.
Fresh air, especially that breathed at the seaside and smelling of seaweed.
Origin: From Ozon, coined 1840 by Christian Friedrich Schönbein, from ὄζον, neuter participle of ὄζω, in reference to its pungent odour.
Ozone, or trioxygen, is a triatomic molecule, consisting of three oxygen atoms. 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. In total, ozone makes up only 0.6 ppm of the atmosphere. Ozone was proposed as a new substance in air in 1840, and named, even before its chemical nature was known, after the Greek verb ozein, from the peculiar odor after lightning storms. Ozone's odor is sharp, reminiscent of chlorine, and detectable by many people at concentrations of as little as 10 ppb in air. Ozone's O3 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. It is therefore used commercially only in low concentrations.
Chambers 20th Century Dictionary
ō′zōn, n. name given to a supposed allotropic form of oxygen, when affected by electric discharges, marked by a peculiar smell.—ns. Ozonā′tion; Ozonisā′tion; Ozonom′eter.—adj. Ozonomet′ric.—ns. Ozonom′etry; Ozō′noscope.—adjs. Ozonoscop′ic; O′zonous. [Gr. ozein, to smell.]
The Nuttall Encyclopedia
is an allotropic form of oxygen, from which it can be developed by electricity, and into which it can be resolved by heat, present in small quantities in the atmosphere, and possessing strong oxidising properties.
U.S. National Library of Medicine
An unstable triatomic form of oxygen, O3, that exists in the atmosphere in varying proportions. It is produced continuously in the outer layers of the atmosphere by the action of solar UV-radiation on the oxygen of the air.
