The oxygen in the air that we breathe is O2. Two oxygen atoms joined together to form a diatomic molecule. It is essential to life. However, there is another form of oxygen where three oxygen atoms join together to make an O3 molecule. We call this triatomic oxygen, ozone. Ozone is present in the upper atmosphere and protects the planet to some extent from harmful ultraviolet radiation from the Sun. However, combustion and other processes at ground level generate ozone as a noxious and toxic pollutant that can cause smog and is deleterious to air quality and so human and environmental health.
