Because oxygen in its natural state is a molecule of two oxygen atoms. Hence O2.
________________________________________________________________
Oxygen is a diatomic molecule, which means it's always found in nature as O2. Oxygen (and the other diatomic molecules) are never one atom because they are so reactive, they always bond with something else, therefore oxygen is O2. Other diatomic molecules are: Hydrogen (H2), Nitrogen (N2), and the halogens (Fluorine, Chlorine, Bromine, and Iodine)
It does not have a generic name or a trade name. It's always just Oxygen. Sorry.
The reactants are always on the left hand side, so H2 and O2.
We breathe in oxygen, which is in the form of O2 molecules.
The oxidation number is 0. The sum of all oxidation number in a molecule that has not charge is always 0. If it has a charge (ion negative or positive) then the sum must be equal to the charge number.
There are 192 grams of oxygen in 6 moles of O2.

O2 sensors are always located on the exhaust system.O2 sensors are always located on the exhaust system.
O2 sensors are always located on the exhaust system.O2 sensors are always located on the exhaust system.
O2 is the chemical symbol for oxygen. if something has O2 in it it has 2 oxygen molecules=)

The chemical formula for oxygen is O2, which means it is made up of two oxygen atoms bonded together.
O2 sensors are always located on the exhaust system.
Coefficient
The chemical formula for oxygen is O2 and for individual oxygen atom its symbol is O. Gases such as oxygen exist as diatomic molecules.
Oxygen has a diatomic molecule and ozone a triatomic molecule.But also monoatomic oxygen exist.
