Nitrogen

Explanation:

Among the countless elements existing in nature, we can highlight some widely used or produced in the industry (which, in turn, are used in other areas). And, among these, nitrogen gas, the component with the greatest amount of oxygen in the atmosphere (it makes up 78% of the atmosphere).

Gaseous nitrogen, which is captured from the atmosphere in the same process as oxygen gas, has a wide application in the chemical, food, electrical and metallurgical industries. N2 is used in large quantities in liquid form, since its gaseous form is used as an inert atmosphere.
