It does have a subscript. 'O2' of oxygen , the figure '2' should be written subscriot; that is slightly smaller and slightly lower that the writing line.
Atmospheric oxygen is a diatomic molecule 'O2' ; two atoms of oxygen combined with a double covalent bond ' O=O '.
No-body 'invented' oxygen !
Oxygen is used in respiration.It act as last electron acceptor.

ctrl = for subscript ctrl shift = for superscript
the subscript g after H2O indicates that it is water vapour, a gas, which is what the subscript g stands for. If there was a subscript s after the H2O, it would mean that H2O is in a solid form as ice. If there was a subscript l it means that H2O is in the liquid form as water.
You are not able to format a single character as subscript, but you can change the entire ledged text to subscript. Right-click on the ledged, select Font, and click on the Subscript option.
Not every chemical formula requires subscript. For example table salt is NaCl, sodium chloride. No subscript. But most chemical formulae do require subscript, such as water, H2O.
Click the Subscript button in the Font group of the Home tab.
superscript 63 and subscript 152 Eu (the super and subscript go before the symbol with superscript on top of the subscript)
The chemical symbol of fermium is Fm; as a subscript in the isotopes symbols is atomic number.
Oxygen does not have a subscript in the formula H2O because it forms a covalent bond with hydrogen atoms to create a stable molecule. The subscript 2 in H2O indicates that there are two hydrogen atoms bonded to one oxygen atom, making the molecule water.
