Is nitrogen lighter than helium?

It's because the hydrogen and helium atoms are lighter than a nitrogen atom. They have fewer electrons, protons and neutrons than nitrogen atoms do, and that makes them lighter (the approximate atomic weight of hydrogen is 1, helium is 4 and nitrogen is 14). ... Therefore, the gases made of lighter atoms are lighter.

Is nitrogen lighter than air?

Nitrogen. Pure nitrogen has the advantage that it is inert and abundantly available, because it is the major component of air. However, because nitrogen is only 3% lighter than air, it is not an obvious choice for a lifting gas.

How many times Hydrogen is lighter than oxygen?

oxygen gas is more heavier than hydrogen gas,as for gases density depends upon the molar mass.So,H2 has more molar mass of 2g/mole than that of oxygen O2 is 32. thus hydrogen gas is 16 times lighter than oxygen gas.
