Lots of things are true about these two elements. You might want to be more specific. Alternatively, if this is a homework question, the answer the teacher is looking for is undoubtedly in your reading material, and you should look there rather than on the internet where you're going to get random answers (some of which may even be true, but none of which are likely to be the answer that actually earns you points).
true
Argon, Carbon Dioxide, Nitrogen, oxygen, hydrogen
Nitrogen is lighter than oxygen
NO2, or nitrogen dioxide.
It is nitrogen, followed by oxygen.
Yes. But nitrogen is inactive.
No. There is more nitrogen. Nitrogen is 78% while oxygen is 21%. The rest is a mixture of other gases.
true
It is not rues at all. Most of the gas inhaled is not oxygen it is nitrogen.
they are both made of protons, neutrons, and electrons
False. Almost all of the oxygen on Earth is found in the oceans.
Good old air contains more Nitrogen than oxygen.
Hydrogen and Nitrogen. Or oxygen and carbon dioxide, or carbon monoxide.
Yes, it is true because the density of oxygen is higher than the density of nitrogen.
No. It would be very bad for us if they did, ad out atmosphere is mostly nitrogen and oxygen. Nitrogen will react with oxygen, but only at high temperatures, and the process actually absorbs more energy than it gives out.
true
They are both made of protons, neutrons, and electrons
