WebbOzone is a gas that is naturally present in our atmosphere. Each ozone molecule contains three atoms of oxygen and is denoted chemically as O 3. Ozone is found primarily in two regions of the atmosphere. About 10% of atmospheric ozone is in the troposphere, the region closest to Earth (from the surface to about 10–16 kilometers (6–10 miles)). WebbInformation on oxygen is summarized in the chart below. Atomic oxygen has three isotopes, 16 O (99.759 %), 17 O (0.0374 %), 18 O (0.2039 %). The most common oxygen species in the atmosphere is triplet dioxygen, a diradical (boiling point = -183 deg C). Singlet dioxygen is diamagnetic with two electrons in one of the pi antibonding orbitals.
