Oxygen compounds Oxygen compounds Aluminum oxynitride (AlON) is a transparent ceramic composed of aluminum, oxygen and nitrogen. It is marketed under the name ALON™ and described in . The material remains solid up to 1200°C, and is harder than glass. When formed and polished as a window, the material currently (2005) costs about $USD10 to $USD15 per square inch. ...more on Wikipedia about "Aluminum oxynitride"
Dioxygen difluoride, O2F2, has a density of 1.45 g/cc. It melts at -163.45 °C and boils at -57.15 °C. ...more on Wikipedia about "Dioxygen difluoride"
Hydrates are compounds formed by the union of water with some other substance, generally forming a neutral body, as certain crystallized salts. If the water is heavy water, where the hydrogen consists of the isotope deuterium, then the term deuterate may be used in place of hydrate. ...more on Wikipedia about "Hydrate"
Hydrogen trioxide or Dihydrogen trioxide (H2O3 or HOOOH) is an unstable molecule, which in water undergoes a retro- 2+2+2 decomposition to form two water molecules and singlet oxygen. The reverse reaction typically does not occur due to the scarcity of singlet oxygen and the difficulty of assembly three molecules into the appropriate transition structure. ...more on Wikipedia about "Hydrogen trioxide"
Oxygen difluoride is a chemical compound whose formula is OF2. The oxygen has an oxidation number of +2, unlike many other oxygen compounds, where it is -2. This substance also reacts very slowly with water to form hydrofluoric acid. As with other compounds of highly electronegative elements, oxygen difluoride is a powerful oxidizer. ...more on Wikipedia about "Oxygen difluoride"
An oxygen fluoride is a compound containing oxygen and fluorine. ...more on Wikipedia about "Oxygen fluorides"
Ozone (O3) is an allotrope of oxygen, the molecule consisting of three oxygen atoms instead of the more stable diatomic O2. ...more on Wikipedia about "Ozone"
Ozonide is an unstable, reactive polyatomic anion O3-, derived from ozone, or an organic compound similar to organic peroxide formed by a reaction of ozone with an unsaturated compound. ...more on Wikipedia about "Ozonide"
Peroxide has three distinct meanings: ...more on Wikipedia about "Peroxide"
Superoxide is a reactive anion and free radical of oxygen, formally O2−. It has an unpaired electron, is not particularly stable, and spontaneously decomposes into peroxide and oxygen over time. It is biologically quite toxic and is used by the immune system to kill invading microorganisms. ...more on Wikipedia about "Superoxide"
Tetraoxygen, also called red oxygen (O4), is an allotrope of oxygen occurring in extremely high pressures (in order of 20 GPa). Under such pressures the normally blue solid oxygen turns deep red, together with great reduction of its volume. Its absorption spectrum suggests the formation of O4 molecules. It is a much more powerful oxidizer than oxygen or ozone, and its properties are being studied for use in rocket fuels and other applications, as it contains more oxygen in a smaller volume. ...more on Wikipedia about "Tetraoxygen"
Water has the chemical formula H2 O, meaning that one molecule of water is composed of two hydrogen atoms and one oxygen atom. It is in dynamic equilibrium between the liquid and solid states at standard temperature and pressure. At room temperature, it is a nearly colorless, tasteless, and odorless liquid. It is often referred to in the sciences as the universal solvent and the only pure substance found naturally in all three states of matter. ...more on Wikipedia about "Water (molecule)"
