O2 Full Form

What is the full form of O2?

O2 is an expression we use for oxygen molecules with 2 atoms. At its purest form, oxygen is an elemental gas that exists at room temperature and is colourless, odourless, and tasteless. Two oxygen atoms combine to form an oxygen molecule, which is where the name O2 originates. Almost every living being on this earth needs oxygen to survive. It is essential for respiration because the body uses oxygen to break down food molecules.

What is O2?

Oxygen is the eighth chemical element. It has the atomic number 8 and the chemical symbol O. It is a very reactive nonmetal element and a chalcogen group member in the periodic table. It is also an oxidising agent that readily produces oxides with most elements and other compounds. After helium and hydrogen, oxygen is the element that is found in the greatest abundance on Earth and in the universe. At ambient pressure and temperature, two of the element's atoms unite to form dioxygen, a diatomic gas with the formula O2.

Uses of O2

Some common uses are as follows:

1. For mining purposes.

2. For manufacturing various chemicals.

3. For rocket propulsion.

4. For the production of stones.

5. For manufacturing glass products.

6. For biological and medical support of living beings.

7. In the treatment of several diseases.
