Background info of oxygen
The symbol for oxygen is "O." Oxygen was discovered in 1774 by Joseph Priestley in England and two years earlier, but unpublished, by Carl W Scheele in Sweden. The name oxygen comes from the Greek word "oxy genes," which means acid forming.
Structure of oxygen
-atomic number: 8
-atomic mass: 15.9994
-8 protons, 8 neutrons, and 8 electrons

Natural sources of oxygen
Oxygen can be found in the human body as H2O, which makes up 60% of the body, in oceans, seas, rivers, ponds, and bays as H2O, and 21% of the atmosphere.
Uses of oxygen
This gas is used in various industrial chemical applications. It is 21% of the atmosphere, and we need it to breathe. It is used to make acids such as sulfuric acid, nitric acid and other compounds. Hot oxygen air is required to make steel and iron in blast furnaces. Some mining companies use it to destroy rocks. Industries use the gas for cutting, welding and melting metals. The gas is capable of generating temperatures of 3000 C and 2800 C. Oxygen turns food into energy. It is in H2O which we are made up to 60% out of and need to drink to survive.
Fun and scientific facts about oxygen
Oxygen's most reactive variant is ozone O3. It is applied in assorted chemical reactions. The goal is to boost reaction rate and oxidation of unwanted compounds. Oxygen is odorless and colorless in gas, pale blue in liquid and solid states.
