Pure oxygen gas contains only oxygen, unlike ordinary air which contains several gases and particles.
Elemental oxygen comprises 21% of the air around us in it's bi-atomic state O2. It also exists as O3 (ozone), and O4 which breaks down to O2.
Oxygen in its combined forms is a component of water, and of many hundreds of mineral compounds and oxides. It is a major component of the earth's crust, and is in fact the most abundant of all elements.
The element oxygen, as O2, makes up 21% of the atmosphere. Another form of the element oxygen is ozone, O3, which also occurs in the atmosphere.
Chlorine is found naturally as sodium chloride in sea water and oxygen is found in the earth's crust in the form of carbonates, oxides and silicates.
It is found in its diatomic elemental form in our atmosphere which contains 21% oxygen. Oxygen is also a component of water (H2O) which are also present in large quantities on Earth.

Silicon.
It is found as Oxygen Gas (O2). This is about 1/4 of the earth's atmosphere (air).
It is found in its diatomic elemental form in our atmosphere which contains 21% oxygen. Oxygen is also a component of water (H2O) which are also present in large quantities on Earth.
