Where is the element oxygen found on earth?

Answer 1

Pure oxygen gas contains only oxygen, unlike ordinary air which contains several gases and particles.

Answer 2

Oxygen is found in the Earth's atmosphere, making up about 21% of the air we breathe. It is also present in water molecules (H2O) and in many minerals and rocks on the Earth's surface. Additionally, oxygen is a key component of living organisms, as it is essential for respiration.

Answer 3

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.

Answer 4

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.

Answer 5

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.

Answer 6

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.
