dinitrogen
Two bonded nitrogens
Dinitrogen is the chemical name for molecular nitrogen—two nitrogen atoms bonded together (N₂).
It constitutes about 78% of Earth's atmosphere.
The term appears mainly in scientific contexts where precision matters: dinitrogen fixation, dinitrogen monoxide.
In everyday speech, people just say nitrogen.
