Most living organisms, including Animals and Plants require oxygen for respiration.

Humans inhale more than 6 billion tone of oxygen each year.

Oxygen in gaseous form is colorless, odorless, and tasteless while liquid and solid oxygen are pale Blue in color.

Excited oxygen is responsible for the bright Red and Yellow-Green colors of the aurora.

Oxygen is a non-metal.

Oxygen gas normally is the divalent molecule O2. Ozone, O3, is another form of pure oxygen.

Oxygen supports combustion. It is an essential factor for burning up the body's toxins.

Diseases in body actually occur when there is a deficiency of oxygen.

Oxygen is paramagnetic.

Approximately 2/3 of the mass of the human body is oxygen.

Excited oxygen is responsible for the bright red and yellow-green colors of the aurora.

Oxygen was the atomic weight standard for the other elements until 1961 when it was replaced by carbon 12.

Oxygen is the most abundant chemical element, by mass, in our biosphere, air, sea and land. It is the third most abundant chemical element in the universe, after Hydrogen and Helium

About 0.9% of the Sun's mass is oxygen.

Oxygen was discovered by Carl Wilhelm Scheele in Sweden in 1771 and then by Joseph Priestley in 1774. It was named by Antoine Laurent Lavoisier in 1774.

Oxygen provides us with 90% of our nutritional Energy, with just 10% coming from the Food we eat.
