In the Greek is where the etymological origin of the word that we are going to analyze next is found: nitrogen. Specifically, we can make it clear that it is formed by the union of the word nitron which means “potassium nitrate” and gene which is equivalent to “generation”. However, it must be made clear that the person who created this term was none other than the French chemist Jean Antonie Chaptal in the year 1790.
It is known as nitrogen to the chemical element characterized by its atomic number 7 and what do i know symbolized with the letter N. It’s about a gas colorless, odorless and tasteless in character that is present in one-fourths of the air in the atmosphere (in its molecular version, recognized as N2).
It should be noted that nitrogen is usually used as refrigerant and is useful in the process of formation of the ammonia which then allows the creation of fertilizers and explosives, among other products. With nitrogen it is also possible to manufacture nitric acid.
Being an inert fluid, nitrogen is often described as azote (namely, “lifeless”) and, in ancient times, even the symbol Az to identify it. It is considered that, officially, it was discovered by the chemist of Scottish origin Daniel Rutherford (1749–1819), who in 1772 unveiled some of its properties.
Nitrogen is the most abundant compound in the atmosphere of our planet, with the 78.1% of its volume. It is also present in the 3% of the elemental structure of the organism of human beings and appears in the remains of specimens belonging to the animal kingdom. Several scientists have also detected some compounds from outer space where the presence of nitrogen is also noted.
This element, on the other hand, is an essential compound of the nucleic acids and of the amino acids. When hydrogen compounds have cyanide ions, they are highly toxic salts that can be fatal.
It is important that we also establish that one of the main studies that have been carried out with nitrogen as the central axis has been that of the effects it has on human health. Specifically, it has been established that the changes that man has generated in the atmosphere, through pollution, have increased the proportions of the elements that make up that one, bringing with them that the individual is, for example, affected by low levels of vitamin TO.
The nitrogen in its liquid version it is kept at a temperature identical to or lower than its boiling temperature (according to measurements, at -195.8 ºC). It can be generated on an industrial scale from fractional distillation and is often used to seal waterways in public works.
It is known as cycle of nitrogenfinally, to the biological and abiotic processes that allow the supply of the element to living beings. The dynamic balance of composition of the biosphere depends on these processes.
This cycle is made up of several clearly delimited phases, the first of which is called Nitrogen fixation and assimilation. It would be followed by ammonification, nitrification and finally what is known as denitrification, which is the one in which the nitrate ion is reduced to diatomic nitrogen.
The last element mentioned, also known as dinitrogen or molecular nitrogen, we can establish that it is a gas that becomes the component in approximately 78% of what is atmospheric air. Among its main hallmarks are that it is colorless, inert and tasteless and that which is used very frequently in what are the different tasks and research in cryogenics.
