If anyone knows alot about the element nitrogen please give me all the info you know because Im going to make a presentation and show it to my sience teacher to see if he will give me extra credit. So some help me please.Who ever gives me the most information will be chosen as the best answer. So work hard on finding this information. ~ kay bye ~

Nitrogen is the most abundant gas in our atmosphere, approximately 78% of it is nitrogen. It liquifies at -195.8 deg C and can be used to make liquid Oxygen. It is inert in its gaseous state and is used in aircraft tyres to reduce the heat generated when an aircraft lands. It can be used in automobiles to reduce heat while driving and helps preserve the life of auto tyres, when doing this it also reduces the losses of gas via the tyre valve and reduces the incidence of flat tyres as a result this is because nitrogen molecules have a larger effective size than the mixture of molecules in the normal compressed air mixture.
Nitrogen disperses oxygen and is therefore very dangerous in high concentrations. When liquid nitrogen is dispensed it is important to therefore keep this in mind especially in enclosed spaces. Also when dispensing liquid nitrogen, as the dispensing hose becomes extremely cold oxygen in the atmosphere surrounding the hose becomes more dense and as oxygen in high concentrations supports combustion there is further danger of explosions and combustion in the area around the dispensing equipment. This means that there is a fire hazard when dispensing liquid nitrogen even though the nitrogen itself is inert.
That's about the limit of my knowledge, I hope it helps you.

The symbol for nitrogen is N and the mass is 14.00674g. N is in group 5A. it exists as N2 when it's a gas (non-metal), meaning it's a diatomic. According to my chemistry book, Chemistry and Chemical Reactivity, it makes up about 3/4 of our atmosphere. It is present in "chlorophyll, proteins, and DNA. Also, it's charge is -3. I think, when poliatomic, it can exist as nitrite (NO_2_^-) or nitrate (No_3_^-).
lol
I am sooooooo already know that
sorry that's all I can do for you.
hope everything works out well........
lol u cheater!!!!!
