Detailed explanation-1: -Nitrogen and oxygen account for 99 percent of the gases in dry air, with argon, carbon dioxide, helium, neon, and other gases making up minute portions.

Detailed explanation-2: -In the atmosphere, nitrogen exists as a gas (N2), but in the soils it exists as nitrogen oxide, NO, and nitrogen dioxide, NO2, and when used as a fertilizer, can be found in other forms, such as ammonia, NH3, which can be processed even further into a different fertilizer, ammonium nitrate, or NH4NO3.

Detailed explanation-3: -Nitrogen and oxygen are the two main gases in our atmosphere. 78% is nitrogen and 21% is oxygen. The remaining 1% mostly contains argon, carbon dioxide, and several other gases like hydrogen, helium, neon, krypton, xenon, methane, ozone, and water vapour.
