Detailed explanation-1: -Nitrogen is the most abundant gas in the atmosphere, comprising about 78% of it. The composition of other gases in the atmosphere is: Oxygen-21% The remaining 1% is composed of argon, carbon dioxide, and few other gases.
Detailed explanation-2: -Air is mostly gas 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: -Nitrogen is an inert gas which makes up 78% of atmosphere. It is inert at normal temperatures. Thus, when lightning sparks, nitrogen interrupts the flow of oxygen to the said inflammable material.
