Oxygen is a colourless gas that exists in large quantities in the air. All plants and animals need oxygen in order to live. The human brain needs to be without oxygen for only four minutes before permanent damage occurs. a gas that has no colour or smell, is present in air, and is necessary for most animals and plants to live. It is a chemical element : symbol O (oxygène, from oxys + -gène ; because it was believed that oxygen forms part of all acids). Gaseous chemical element, chemical symbol O, atomic number

Often seen as using the chemistry abbreviation 02, gas vital for all life on this planet; makes up about 21% of the air by volume
One of the nine macronutrients Oxygen is a major component of organic molecules, which are the building blocks of all organisms Humans breath air, plants "breath" carbon dioxide (CO2) Respiration breaks CO2 into carbon and oxygen for use Plants also take in oxygen through their roots
It constitutes 21% (by volume) of air and more than 46% (by weight) of Earth's crust, where it is the most plentiful element. It is a colourless, odourless, tasteless gas, occurring as the diatomic molecule O2. In respiration, it is taken up by animals and some bacteria (and by plants in the dark), which give off carbon dioxide (CO2). In photosynthesis, green plants assimilate carbon dioxide in the presence of sunlight and give off oxygen. The small amount of oxygen that dissolves in water is essential for the respiration of fish and other aquatic life. Oxygen takes part in combustion and in corrosion but does not itself burn. It has valence 2 in compounds; the most important is water. It forms oxides and is part of many other molecules and functional groups, including nitrate, sulfate, phosphate, and carbonate; alcohols, aldehydes, carboxylic acids, and ketones; and peroxides. Obtained for industrial use by distillation of liquefied air, oxygen is used in steelmaking and other metallurgical processes and in the chemical industry. Medical uses include respiratory therapy, incubators, and inhaled anesthetics. Oxygen is part of all gas mixtures for manned spacecraft, scuba divers, workers in closed environments, and hyperbaric chambers. It is also used in rocket engines as an oxidizer (in liquefied form) and in water and waste treatment processes
A colorless, odorless, tasteless gas Most life on earth requires oxygen to live Animals breathe oxygen out of the air or water Plants also need oxygen, even though they produce oxygen by photosynthesis
Oxygen is one of the chief constituents of the atmosphere of which it forms approximately one fifth It is odourless and invisible Although oxygen itself does not burn it is extremely efficient in supporting combustion, nearly all other chemical elements combine with it under evolution of heat It has many uses in industry and is essential to the BOS (Basic Oxygen Steelmaking Process)
Colorless odorless gas that makes up about 20 percent of the air we breathe; it is essential to life because it is used for the chemical reactions that occur in the cells of the body

An oxygen mask is a device that is connected to a cylinder of oxygen by means of a tube. It is placed over the nose and mouth of someone who is having difficulty in breathing in order to help them breath more easily. A masklike device placed over the mouth and nose and through which oxygen is supplied from an attached storage tank
A canopy placed over the head and shoulders or over the entire body of a patient to provide oxygen at a higher level than normal. a piece of equipment shaped like a tent that is put around people who are very ill in hospital, to provide them with oxygen
A group of nuclear reactions, that involve the interaction of protons with carbon, nitrogen and oxygen nuclei, thought to be the main source of energy in main-sequence stars of greater than 1.4 solar mass
Steelmaking method in which pure oxygen is blown through a long, movable lance into a bath of molten blast-furnace iron and scrap, in a steel furnace with a refractory lining called a converter. The oxygen initiates a series of heat-releasing reactions, including the oxidation of such impurities as silicon, carbon, phosphorus, and manganese; carbon dioxide is released, and the oxidation products of the other impurities form molten slag that floats on the molten steel. The advantages of using pure oxygen instead of air in refining iron into steel were recognized as early as the 1850s (see Bessemer process), but the process could not be commercialized until the late 1940s, when cheap, high-purity oxygen became available. Within 40 years it had replaced the open-hearth process and was producing more than half of all steel worldwide. Commercial advantages include high production rates, less labour, and steel with a low nitrogen content
The amount of oxygen required by aerobic microorganisms to decompose the organic matter in a sample of water, such as that polluted by sewage. It is used as a measure of the degree of water pollution. Also called biological oxygen demand
[ 'äk-si-j&n ] (noun.) 1790. Borrowed from French oxygène (originally in the form principe oxygène, a variant of principe oxigine ‘acidifying principle’, suggested by Lavoisier), from Ancient Greek ὀξύς (oxus, “sharp”) + γένος (genos, “birth”), referring to oxygen's role in the formation of acids.
