they help balance the level of nitrogen in the soil and atmosphere.
It depends. There could be a factory in the vicinity that is pumping nitrogen into the air because of the chemical processes involved. There could even have been an explosion somewhere near increasing the level of nitrogen in the atmosphere. But nitrogen is, of course, also an intrinsic element in the socalled nitrogen cycle in nature, and any inbalance in this regard -- the freeing of more or less nitrogen than could be considered "normal" from its fixations in the soil or elsewhere -- could be a clear sign that something is wrong with the environment.
These gases are: nitrogen (78,084 %), oxygen (20,9476 %), water vapors (variable concentration), argon (0,934 %), carbon dioxide (0,0314).
the valency of nitrogen is 3symbol:Natomic mass:14
The atmosphere is primarily composed of Nitrogen (N2), which accounts for 78%. Oxygen follows, accounting for 20% of its volume, with argon less than 1%. The remainder is composed of particulates and trace gases, including water vapor.
By volume it is nitrogen. Nitrogen form ~ 79% Oxygen forms ~ 20% The remaing 1% is composed of water vapour, carbon dioxide, methane, ammonia, sulphur dioxide, nitrogen dioxide, and the noble(inert) gases. Although, humans live in 'fear and trembling' on the level of carbon dioxide in the atmopsphere, it is actually extremely low, by volume, compenent of the atmosphere.
Because due to the over pollution and cutting down the tree's level of Oxygen is decreasing .The level of Nitrogen always remains constant in the atmosphere . The level of Nitrogen doesn't' depend on the level of the Oxygen level.
The Troposphere is the lowest level of Earth's Atmosphere.

Most of the nitrogen in the atmosphere came from solar evaporation of nitrogen rich elements in the soil of the early earth. It now makes up almost 80% of the atmosphere.
Most kinds of weather occurs in the troposphere, the lowest level of the atmosphere.
