About 20% more than Oxygen at around 50%.
No. Nitrogen is triply bonded, and is much more stable at "standard" temperatures than the more electronegative oxygen is.
Nitrogen is a very chemically stable gas which makes it more difficult for most plants to use, thus it is much more abundant in the atmosphere than the ground.
Because lots of stuff (plants and plankton and algae) make it. Not as much stuff make carbon and sulfur and nitrogen

The five most abundant elements that make up atomic matter are; Hydrogen, Helium, Oxygen, Carbon and Neon. Hydrogen is by far the most abundant element. There is three times as much Hydrogen than the next most abundant element, Helium.
Oxygen is much more reactive than nitrogen, somewhat more common than nitrogen, and tends to form much more stable compounds than nitrogen.
21% Oxygen, 78% Nitrogen and 1% Other Gases
Oxygen keeps animals alive, Nitrogen is not much use.
The air is made up, mostly, of oxygen and nitrogen.. Air is 78 % nitrogen, 21 % oxygen, about 1 % argon, and a whole raft of other gases present in even smaller amounts..
Because that's how much there is, even if there were more oxygen in air than nitrogen this would be unhealthy!
without nitrogen our bodys would over oxygenate (get to much oxygen). nitrogen is important for plants, after all they breath in nitrogen and breath out oxygen.
