Oxygen vs. Ozone

Oxygennoun

A chemical element (symbol O) with an atomic number of 8 and relative atomic mass of 15.9994.

Oxygennoun

Molecular oxygen (O2), a colorless, odorless gas at room temperature.

Oxygennoun

(medicine) A mixture of oxygen and other gases, administered to a patient to help him or her to breathe.

Oxygennoun

(countable) An atom of this element.

Oxygennoun

A colorless, tasteless, odorless, gaseous element of atomic number 8, occurring in the free state in the atmosphere, of which it forms about 23 per cent by weight and about 21 per cent by volume, being slightly heavier than nitrogen. Symbol O. Atomic weight 15.9994.

Oxygennoun

Chlorine used in bleaching.

Oxygennoun

a nonmetallic bivalent element that is normally a colorless odorless tasteless nonflammable diatomic gas; constitutes 21 percent of the atmosphere by volume; the most abundant element in the earth's crust

Oxygennoun

a colourless, odourless reactive gas, the chemical element of atomic number 8 and the life-supporting component of the air.

Oxygen

Oxygen is the chemical element with the symbol O and atomic number 8. It is a member of the chalcogen group in the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds.

Ozonenoun

(inorganic chemistry) An allotrope of oxygen (symbol O₃) having three atoms in the molecule instead of the usual two; it is a toxic gas, generated from oxygen by electrical discharge.

Ozonenoun

Fresh air, especially that breathed at the seaside and smelling of seaweed.

Ozoneverb

(transitive) To treat with ozone.

Ozonenoun

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.

Ozonenoun

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

Ozone (), or trioxygen, is an inorganic molecule with the chemical formula O3. It is a pale blue gas with a distinctively pungent smell.
