ozone Unstable, pale-blue, gaseous allotrope of oxygen, formula (O3). It has a characteristic pungent odour and decomposes into molecular oxygen. It is present in the atmosphere, mainly in the ozone layer. Prepared commercially by passing a high-voltage discharge through oxygen, ozone is used as an oxidizing agent in bleaching, air-conditioning and purifying water. See also allotropy

Each form (an allotrope) can have different chemical properties but can be changed into another allotrope – given suitable conditions. Examples of allotropes are molecular oxygen and ozone, white and yellow phosphorous, and graphite and diamond (carbon).
