Oxygen is a chemical element, in the periodic table. At standard temperature and pressure, oxygen is found as a gas consisting of two oxygen atoms, chemical formula O2. This oxygen is an important component of air, produced by plants during photosynthesis and is necessary for animals' respiration?.

Oxygen comprises about 87% of the oceans (as H2O, water) and 20% of the atmosphere (as O2, molecular oxygen, or O3, ozone). Due to its electronegativity, oxygen easily forms chemical bonds with many other elements (which is the origin of the original definition of oxidation). Famous examples are carbon dioxide (CO2), alcohols (X-OH) and [carbon acids]? (X-COOH).

Old article, please merge * A chemical element, in the periodic table Oxygen has the symbol O and atom number 8. * A gas having molecules consisting of two oxygen atoms, chemical formula O2. Oxygen is an important component of air. This gas is produced by plants during photosynthesis and is necessary for animals' respiration?. * The process by which oxygen reacts with other elements or chemical compunds is called oxidation, though the term has since been generalised by chemists to also refer to electrochemistry processes not involving oxygen. * Oxygen is not necessary for oxidation the way chemists use the term (removal of electrons from something). I'm not quite sure how to change the sentence, though, so that it still makes sense.
