Introduction

oxygen element

Oxygen

[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.
