If you are asking whether nitrogen is less dense than air and will float on top of it, then yes, nitrogen is "lighter," albeit only slightly. More accurately, nitrogen, which is a constituent gas of air, is less dense than air, not lighter. The density of air at standard temperature and pressure is 1.292 kg/m3. The density of nitrogen is 1.251 kg/m3.

∙ 11y agoNo, nitrogen is not heavier than carbon dioxide. A nitrogen molecule is significantly lighter than a carbon dioxide molecule (28 vs. 44 amu).
You also need to note the density at STP. Nitrogen gas is also less dense, further meaning that it is lighter.

No, although the most of air is nitrogen, pure N2 (28.0 g/mol) is lighter because the other 19% O2 (32.0 g/mol) is heavier. The 1% Ar (18 g/mol) alone cannot compensate that.

What percentage of hydrogen is lighter than air?
100% of hydrogen is lighter than air
When balloons are filled with this they are lighter than air?
Hot air, hydrogen or helium are lighter than cold air.
A basic gas lighter than air?
Hydrogen and Helium are both lighter than air.
Why is moist air associated with low air pressure?
Warm, moist, humid, air associated with a low pressure system is actually lighter than dry air - owing to the fact that hydrogen molecules in water vapor (H20) are lighter than Oxygen or Nitrogen molecules. This moist air rises - causing air pressure to be relatively low compared to surrounding air.
Greenhouse gases are obviously lighter than air How then are they measured by weight How does one weigh something that is lighter than air?
Greenhouse gasses are NOT "obviously lighter than air"; carbon dioxide is significantly heavier than air.One way to weigh something that's lighter than air is to weigh it in a vacuum.
What happens when water vapor is lighter than nitrogen or oxygen?
Water vapor is a gas so it is in the air. Nitrogen and nitrogen are in the air too, but there is more nitrogen than anything in the air. I believe it rises because it is lighter, like a balloon filled with helium.
Why is nitrogen heavier than air?
No. The atmosphere is roughly 80% N2, 20% O2, and about 1% of other trace gases. The molecular mass of N2 is about 28, the molecular mass of O2 is about 32. So, no O2 is not lighter than air, it is slightly heavier.
What is lighter oxygen or nitrogen?
Nitrogen is lighter than oxygen
What happens because water vapor molecules are lighter than nitrogen or oxygen molecules?
humid air is lighter that an equal volume of dry air at the same temperature.
Is air lighter than heluim?
The composition of Earth's atmosphere is mostly nitrogen, carbon dioxide, and oxygen. All of these elements are denser than helium, and therefore it tends to rise.
Why is it that the nitrogen have greater amount than oxygen?
nitrogen is lighter than oxygen
Why was the airplane harder to invent than the hot air balloon?
The balloon is lighter than air.
What percentage of hydrogen is lighter than air?
100% of hydrogen is lighter than air
Is methane lighter than air?
Yes methane is lighter than air because it is less dense than air.
Is argon lighter than air?
No Argon is not lighter than air. Argon is 25% more dense than air.
When balloons are filled with this they are lighter than air?
Hot air, hydrogen or helium are lighter than cold air.
What are some lighter than air aircrafts?
blimp or hot air balloons are lighter than air crafts
