5. When Nitrogen Is Discovered
Nitrogen was discovered by the Scottish physician Daniel Rutherford in Rutherford removed oxygen and carbon dioxide from air and showed that the residual gas would not support combustion or living organisms. While other scientist also tried really hard to find out about nitrogen, the failed a lot and loose hope, Rutherford called nitrogen as a noxious air. But Scheele, Cavendish, Priestley, and the others at about the same time studied "burnt" or "dephlogisticated" air.
Nitrogen is the fifth most abundant element that create and make up78% of the earth atmosphere. The nitrogen contains al least 4,000 trillion tons of the gas.that is why nitrogen is called a Noble Gas which makes it for the most part inert unless subjectedto high temp. or pressure.

6. Nitrogen-N
Nitrogen is simplify to N, so that it is easier for people to memorize and learn just like the other elements.
Nitrogen or usually called as N can exist in multiple oxidation states. N is contains a lot of unique and unique component but one of them areprotoplasm.      

7. What Is A Nitrogen
Nitrogen is a common normally colourless, tasteless and mostly diatomic non-metal gas. In a Nitrogen has a various minerals and in all proteins and used in a wide variety of important manufacture and also included including ammonia, nitric acid, TNT. Nitrogen is located at the group of 15 in the periodic table. Nitrogen is usually known as a non-metals that is not easily to to conduct heat, electricity and reflect light. Non-metallic elements exist, at room temperature, in two of the three states of mattersuch as gasses and solids.

8. Double Facts About Nitrogen
Uses Of Nitrogen
Interesting Facts
Gunpowder
Fertilizer
Rocket Fuels
The total mass of nitrogen in an average 70kg human is 1.8kg
He sound you hear when you crack your knuckles is actually nitrogen gas bubbles popping
It is an ingredient in laughing gas

9. Effect Of Nitrogen
Nitrogen may have adverse effects on the vitality of plants. Nitrogenous air pollutants and fertilizer.In many ways, Nitrogen can effect our environment a lot, and they are the atmosphere, bye the use of nitrogen can help the fasten the global warming. But on the other hand, nitrogen could help us in our daily work too.
