Nitrogen gas facts

  • Nitrogen gas is a colorless, odorless, and largely unreactive gas made of two nitrogen atoms.
  • It makes up about 78 percent of Earth's atmosphere by volume and is used to make ammonia, to protect packaged food, and as liquid nitrogen for freezing.
  • The triple bond holding its two atoms together is one of the strongest chemical bonds known, which explains why nitrogen gas reacts so reluctantly.
