Are there gases lighter than helium?

hydrogen is another gas lighter than air; it is even lighter than helium.

Which is lighter, hydrogen or helium?

hydrogen and helium

Hydrogen and helium are the most commonly used lift gases. Although helium is twice as heavy as (diatomic) hydrogen, they are both much lighter than air, so the difference is negligible.

Is nitrogen an inert gas?

Molecular nitrogen is a colorless, odorless, tasteless, Inert gas at normal temperature and pressure. About 78% of Earth’s atmosphere is nitrogen. The strong triple bonds between atoms in molecular nitrogen make this compound difficult to break down, making it nearly inert.
