Oxygen is a chemical element with symbol O and atomic number 8. It is a member of the chalcogen group on the periodic table and is a highly reactive nonmetal and oxidizing agent that readily forms oxides with most elements as well as other compounds.
Oxygen dissolves more readily in water than nitrogen, and in freshwater more readily than seawater. Water in equilibrium with air contains approximately 1 molecule of dissolved O2 for every 2 molecules of N2, compared with an atmospheric ratio of approximately 1:4.
Both liquid and solid O2 are clear substances with a light sky-blue color caused by absorption in the red (in contrast with the blue color of the sky, which is due to Rayleigh scattering of blue light). High-purity liquid O2 is usually obtained by the fractional distillation of liquefied air Liquid oxygen may also be condensed from air using liquid nitrogen as a coolant.
The spectroscopy of molecular oxygen is associated with the atmospheric processes of aurora, airglow andnightglow. The absorption in the Herzberg continuum and Schumann–Runge bands in the ultraviolet produces atomic oxygen that is important in the chemistry of the middle atmosphere. Excited state singlet molecular oxygen is responsible for red chemiluminescence in solution.
Due to its energy content, O2 is used by complex forms of life, such as animals, in cellular respiration. Other aspects of O2 are covered in the remainder of this article.

|Life support and recreational use||An application of O2 as a low-pressure breathing gas is in modern space suits, which surround their occupant's body with pressurized air. These devices use nearly pure oxygen at about one third normal pressure, resulting in a normal blood partial
pressure of O2.
|Industrial||Smelting of iron ore into steel consumes 55% of commercially produced oxygen. In this process, O2 is injected through a high-pressure lance into molten iron, which removes sulfur impurities and excess carbon as the respective oxides, SO2 and CO2.|
|Chemical||Ethylene is reacted with O2 to create ethylene oxide, which, in turn, is converted into ethylene glycol; the primary feeder material used to manufacture a host of products, including antifreeze and polyesterpolymers.|
|Other||Oxygen is used in medical applications, metal cutting and welding, as an
oxidizer in rocket fuel, and in water treatment.
