Oxygen Between discovery and properties




Oxygen between discovery and properties
The discovery of oxygen by the Swedish pharmacist Carl William Shelly almost before 1773, was not
published before the independent discovery of the world Joseph Priestley on August 1, 1774, which called the gas name of the opposite of the phylogenetic. Priestley published his work in 1775 and Chile in 1777, and Priestley usually takes interest because he published first.
 Of the elements that evoke gaiety, so it is used in resorts until modern times. Also noted are the columns of oxygen so far in concerts. In the 19th century it was mixed with nitrous oxide to make a kind of analgesics, and the use of some of these analgesics until now.
Oxygen is often used as an oxidizer, and there is no higher element in the electrolysis than fluorine. Liquid oxygen is used as an oxidizing agent in the propulsion of rockets. Oxygen is also essential in breathing, and therefore has a key role in medicine. Mountain climbers and those using the aircraft also have additional oxygen supplies. Oxygen is also used in welding. In the manufacture of both steel and methanol.






Liquid oxygen and steel have a light blue color, both magnetic and strong. Liquid oxygen is often obtained from partial distillation of liquefied air. Both O3 and solid steel have a dark blue color.




Another oxygen-based form, O4, a dark red solid material obtained by the pressure of O2 was detected by 20 GPa. It has been studied for use in rocket fuel and similar applications, an oxidizing substance stronger than O2 or O3.





Oxygen is an essential air compound, made up of plants during photosynthesis processes, and is important for breathing in airborne organisms in their breathing. The word oxygen is derived from two Greek words that are acidic and acid. This name was chosen in the 18th century because it was believed that all acids contain oxygen. The definition of acid was then changed to the fact that acid should not contain oxygen in its molecular structure.

In normal conditions of temperature and pressure, oxygen is present in the gaseous state. Oxygen consists of two bioluminescent molecules of O2 form. O2 has two forms according to energy: the less energy form, often the mono-bond and the higher-energy form is a mono-bond molecule.
