Detailed explanation-1: -Therefore, nitrogen is the most abundant gas in the atmosphere and makes up 78% of the air.
Detailed explanation-2: -Air is mostly gas It’s a mixture of different gases. The air in Earth’s atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen. Air also has small amounts of other gases, too, such as carbon dioxide, neon, and hydrogen.
Detailed explanation-3: -’ Nitrogen makes up 78 per cent of the air we breathe, and it’s thought that most of it was initially trapped in the chunks of primordial rubble that formed the Earth. When they smashed together, they coalesced and their nitrogen content has been seeping out along the molten cracks in the planet’s crust ever since.
Detailed explanation-4: -Due to the high value of mobility, nitrogen gas is less trapped in the soil of the earth as compared to oxygen which is required for breathing. Hence, though for respiration, oxygen is required but the higher proportion is of nitrogen which is around 78% of the total air composition.
Detailed explanation-5: -In fact, the troposphere contains three-quarters of the mass of the entire atmosphere. The air here is 78% nitrogen and 21% oxygen. The last 1% is made of argon, water vapor, and carbon dioxide.
