By definition, we have to:
Nitrogen is a chemical element where we can find in the periodic table that has an atomic number of 7, its symbol N, and its atomic weight is 14,006.
Under normal conditions it forms a diatomic gas that constitutes about 78% of the atmospheric air.
Among the applications we have:
Nitrogen is a little reactive gas, which is used industrially to create protective atmospheres and as a cryogenic gas to obtain temperatures of around 78K in a simple and economical way.
Answer:
Nitrogen gas consists of diatomic gas which constitutes about 78% of the atmospheric air.
