The first necessary step to begin to analyze in depth the meaning of the term hydrogen is to determine its etymological origin. In doing so we discover that it emanates from the Greek, specifically from the word "hydrogenium". This is made up of two clearly differentiated parts: "hydro", which is synonymous with "water", and "genos", which is equivalent to "generator".
He hydrogen is the chemical element from atomic number 1 . It is the lightest of the elements with an atomic mass of 1.00794 (7) u and of the most abundant of the universe and of the earth's crust (constitutes 83.9% of the visible matter). In the atmosphere, hydrogen is found as a colorless, odorless and flammable gas, in its molecular form H2.
He protio and the deuterium they are the natural isotopes of hydrogen. The most common in the nature It is the protium, which has a single proton and does not have any neutrons. He tritium , on the other hand, is an artificial isotope of hydrogen.
Combined with oxygen, the hydrogen form the Water . The molecules of this essential substance for life are formed by two hydrogen atoms and one oxygen atom. Hydrogen, therefore, can be obtained from water by a process known as electrolysis .
It should be noted that hydrogen is present in most organic substances and acids. Even the stars , in their main cycle, they are formed by hydrogen in the plasma state.
Likewise, we cannot ignore other terms that use the word at hand. Thus we find what is known as a hydrogen pump, which is also called a thermonuclear pump or thermal fusion pump. It is a weapon of mass destruction and the first one that existed was exploded in November 1952 under the name of Ivy Mike. In one of the Marshall Islands, located in the Pacific Ocean, it was where it detonated in an operation called Ivy. Its results were serious damage to the ecosystem and the birth of a crater more than 40 meters deep.
Currently we have to say that there is also what is known as liquid hydrogen. This, which is usually represented under the abbreviation LH2, is used primarily within the space environment as fuel for the different ships. The fact that there is a risk that the tanks that conserve it may explode, due to the difficulty of its retention in them, is what is causing new ways to be investigated to save it.
All this without forgetting that there is also what is hydrogen peroxide, commonly called hydrogen peroxide.
Hydrogen is used as gas (It can be applied in the refining of fossil fuels), in the production of ammonia and to hydrogenate oils or fats.
Experts say that hydrogen is the element that generates the most power in the energy / weight ratio compared to any fuel. On the other hand, hydrogen as fuel does not generate contamination since it only releases water vapor after combustion. That is why it is expected that hydrogen cars Be very popular in the future.
