Ozone - Wikipedia
Ozone (/ ˈ oʊ z oʊ n /) (or trioxygen) is an inorganic molecule with the chemical formula O 3. 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 O 2, breaking down in the lower atmosphere to O 2 .
What is Ozone? | US EPA - U.S. Environmental Protection Agency
Ozone (O3) is a highly reactive gas composed of three oxygen atoms. It is both a natural and a man-made product that occurs in the Earth's upper atmosphere. (the stratosphere) and lower atmosphere (the troposphere). Depending on where it is in the atmosphere, ozone affects life on Earth in either good or bad ways.
Ozone - American Lung Association
Ozone (also called smog) is one of the most dangerous and widespread pollutants in the U.S. It may be hard to imagine that pollution could be invisible, but ozone begins that way. As ozone concentrates and mixes with other pollutants, we often call it by its older, more common name—smog.
Ozone | Definition, Properties, Air Pollution, Importance, Structure ...
Ozone is a triatomic allotrope of oxygen (a form of oxygen in which the molecule contains three atoms instead of two as in the common form) that accounts for the distinctive odor of the air after a thunderstorm or around electrical equipment.

Ozone layer | Description, Importance, & Facts | Britannica
ozone layer, region of the upper atmosphere, between roughly 15 and 35 km (9 and 22 miles) above Earth’s surface, containing relatively high concentrations of ozone molecules (O 3).
What Is Ozone? Definition and Facts - Science Notes and Projects
Ozone is an inorganic oxygen molecule with the chemical formula O 3. It is a reactive allotrope of oxygen that also goes by the name trioxygen. Ozone protects the planet from harmful ultraviolet radiation, yet is also acts as a pollutant near the Earth’s surface and carries health risks.
Ground-level ozone pollution poses growing threat to planetary health
Ozone harms plants and forests, worsens global warming. Ozone is a greenhouse gas and it’s estimated that around 0.2° Celsius (0.36° Fahrenheit) of current warming globally is due to ozone ...
