This is a site all about
| [n]: a colorless tasteless odorless gaseous element, occurring naturally in air, water, and most minerals and organic substances, and essential to plant and animal life. |
Oxygen is ubiquitous for life on earth. Molecular oxygen is diatomic (O-O) existing as a gas and is what sustains most life on earth (atmosphere = 21% O2). Chemical oxygen is found incorporated in pretty much everything else such as metal oxides, minerals, proteins, water etc. Oxygen is therefore fundamental to life on this planet. |
This site was designed to explain all the marvelous properties of oxygen and I hope you take some time to go over this.

| (This site wont hurt you. Oxygen is an oxidiser. It wont burn by itself or explode, but it will greatly accelerate combustion. This means if you are buring a fuel it will burn this very fast. So depending how much there is you can have an explosion of the fuel. So treat it with care.) |

Aristotle's Story The importance of Oxygen for life was perhaps first gleaned by Aristotle. Aristotle introduced a philosophical proposal suggesting that heaven and earth was derived into the four elements: Fire, Water, Earth and Air. It was many hundred of years latter that importance of oxygen was realized as central to all of these states. |
