Meaning of Oxygen
What is Oxygen:
Oxygen is a gaseous, colorless, odorless and tasteless chemical element, abundant in the earth's crust, in the atmosphere and the oceans, which is essential for life. The word is made up of the Greek words ὀξύς (oxys), which means ‘acid’, and γένος (genus), ‘origin’, ‘lineage’, ‘clan’. Formerly, it was believed that oxygen was necessary to produce acid, hence its name, which would literally translate: "that produces acid."
In the periodic table, it is represented with the symbol O and is part of the group Vla, of the family of amphigens or chalcogens. Its atomic number is 8 and its atomic mass is 16.
As a gas, it is heavier than air, constituting a fifth of it in its molecular form O2. It is also part of water, oxides, almost all acids and organic substances, and is present in our body and in all living beings. It is essential for the respiration of animal and plant species (photosynthesis), and in the generation of carbon dioxide (CO2). It is very reactive, and activates the combustion processes. Gathered in a composition of three atoms (O3) it is known as ozone, the gas that constitutes the ozonosphere, a vital atmospheric layer to protect us from the sun's ultraviolet radiation.
The expression "give oxygen" is also used to refer to the need to give life or invigorate a situation. Likewise, the expression "oxygen balloon" is used in an equivalent sense: "The point rescued as a visitor is a oxygen balloon for the team ”.
