O 2 (g) + F 2 → O 2F 2 (g) Reaction with Acids (O 2) can reacts with fluorine and forms dioxygen difluoride, where it requires irradiation of a mixture at Low pressure (10-20 mm Hg) and Low temperature (77 – 90 K). (O 2) doesn’t reacts with water under normal conditions, but dissolved in the water (30 g/l (20 OC). (O 2) gas does not react with itself or nitrogen under normal circumstances, but if it exposed to Ultra Violet (UV) light or an electric discharge, then Ozone (O 3) is formed:ģ O 2 (g) → 2 O 3 (g) Reaction with Water Grid parameters: a=5.403 Å, b=3.429 Å, c=5.086 Å, β=135.53Įlectron affinity: 141 kJ/mol Nuclear Properties of OxygenĬhemical Reactions of Oxygen Reaction with Air The ionization potential of an atom: 13.56 eV Sound Speed: 330 m/s (gas) Atomic Properties of Oxygen Molar magnetic susceptibility: 42.71×10 -9 m 3/mol Physical Properties of Oxygenĭensity: 1.429 g/L (at STP) 1.141 g/cm 3 (In Liquid at B.P) Mass magnetic susceptibility: 1335×10 -9 m 3/kg Volume magnetic susceptibility: 0.00000190772 Magnetic susceptibility (x mol): +3449×10 -6 cm 3/mol Thermal conductivity: 0.02658 W/(m∙K) Magnetic Properties of Oxygen Oxygen Electron Configuration Thermal Properties of Oxygen

Ozone is presence in the atmosphere (amounting to the equivalent of a layer 3 mm thick under ordinary pressures and temperatures) as a shield layer of earth, which helps to prevent from harmful ultraviolet rays comes from the sun to the earth’s surface. Ozone (O 3) is a highly active compound, which is formed by the action of an electrical discharge or ultraviolet light on oxygen.

It is the essential element in the respiratory processes of most of the living cells and as well as in combustion processes. The solid and liquid forms of element are a pale blue color and are strongly paramagnetic. Oxygen is odorless, colorless, and tasteless gas.
