The two major components of the earth's atmosphere are nitrogen and oxygen. There is also trace amounts of hydrogen, carbon dioxide, and other gases.
21% Oxygen 79% Nitrogen Trace amounts of other gasses
78% of the Earth's atmosphere is Nitrogen. Another 21% is oxygen, and the final 1% are other gases found is small amounts such as carbon dioxide, helium and methane.
Molecular oxygen is a bit over a fifth of the Earth's atmosphere, and molecular nitrogen is a bit under four-fifths of the Earth's atmosphere. There are also small amounts of oxygen and nitrogen in other atmospheric components such as carbon dioxide and ammonia.
Earth's atmosphere is mostly made up of nitrogen, which makes up 79 percent. The atmosphere contains 20 percent oxygen and 1 percent other gases.
No, the Nitrogen in the air has probably always been there (because nitrogen is rather inert), but originally Earths atmosphere was reducing (it had no free Oxygen) and probably contained large amounts of CO2 and hydrocarbons. The present atmosphere on Earth is the product of biological processes which have slowly introduced free Oxygen into the Oceans and then the atmosphere - life made Earth habitable for life!
Yes, in varying amounts
About 78% of it is nitrogen. Another 21% of the atmosphere is oxygen, and 1% are other gasses found in very small amounts.

The atmosphere of Mars is mostly carbon dioxide, rather like that of Venus, but much thinner.. It has smaller amounts of argon and nitrogen with trace amounts of methane.
Oxygen, nitrogen, helium and trace amounts of argon. ( among other trace amounts )
The composition of Saturn's atmosphere is primarily hydrogen and helium. There are trace amounts of oxygen, methane, ammonia and nitrogen.

The outgassings of the Earth was stripped away by solar winds early in the history of the planet until a steady state was established, the first atmosphere. Based on today's volcanic evidence, this atmosphere would have contained 80% water vapor, 10% carbon dioxide, 5 to 7% hydrogen-sulfur, and smaller amounts of nitrogen, carbon monoxide, hydrogen, methane and inert gases.
