What element has the symbol 'N'?
Answer
Nitrogen
The story behind the answer
The symbol N stands for Nitrogen. The other options have different symbols: Neon is Ne, Nickel is Ni, and Nihonium is Nh. Nitrogen (atomic number 7) is a colorless, odorless gas that exists mainly as N2 and makes up about 78% of Earth’s atmosphere.
Why it matters: Nitrogen is essential for life—it's in amino acids, proteins, and DNA. Humans industrially “fix” nitrogen into ammonia (NH3) via the Haber–Bosch process to make fertilizers. Memory tip: think “N in the air” as N2, and “N in NH3 and DNA.” Also, N is from Nitrogenium; Lavoisier called it azote (“no life”) because N2 doesn’t support breathing or burning.
