Oxygen

Oxygen, which makes up 21 percent of the earth's atmosphere, supports life and makes combustion possible.

The most abundant of all elements on earth, oxygen accounts for 85 percent of the earth's oceans and, as a component of most rocks and minerals, 46 percent of its solid crust. In addition, it constitutes 60 percent of the human body.

Oxygen reacts with all elements, except noble gases, to form compounds called oxides. The rate of reaction - known as oxidation - varies. For example, magnesium oxidizes very rapidly, igniting spontaneously in air. However, noble metals, such as gold and platinum, oxidize only at very high temperatures.
Although oxygen itself is nonflammable, it enhances combustion and enables all materials that are flammable in air to burn much more vigorously. These combustion-supporting properties account for its use in many industrial applications.
