You probably meant “air” and “nitrogen.” Short answers:

- Air is not an element or a compound — it’s a mixture of gases (mainly nitrogen ~78%, oxygen ~21%, argon ~0.93%, CO2 ~0.04% plus water vapor and traces).
- Nitrogen is an element (chemical symbol N, atomic number 7). In nature it usually appears as the diatomic molecule N2 (two N atoms bonded together), which is still the same element — not a compound. Nitrogen can also be part of compounds (e.g., ammonia NH3, nitrates NO3−).
