Discovered by Daniel Rutherford in 1772 Nitrogen makes up 78% of the air, by volume Nitrogen molecules give the orange-red, blue-green, blue-violet, and deep violet shades to the aurora. its nickname is azote, meaning without life its active compounds are found in foods, poisons, fertilizers, and explosives Nitrogen can also be easily prepared by heating a water solution of ammonium nitrite When nitrogen is heated, it combines directly with magnesium, lithium, or calcium; when mixed with oxygen and subjected to electric sparks

The element is important to live because it helps growth.It also important to live reproduction of plants and animals it also important to people because muscles,tissue,organs.

One way nitrogen enters the cycle is as inorganic nitrogen from the atmosphere and factories. The concern with these forms is that the incremental amount of nitrates they add to the nitrogen cycle may threaten groundwater. Nitrogen can also harm not just plants and water but it can also harm pregnant animals and infant children which can cause the “Blue Baby” syndrome which can also cause internal suffocation.
