Nitrogen | N2 | CID 947 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more.

At standard temperature and pressure, two atoms of the element bond to form N 2, a colourless and odourless diatomic gas. N 2 forms about 78% of Earth's atmosphere, making it the most abundant chemical species in air. Because of the volatility of nitrogen compounds, nitrogen is relatively rare in the solid parts of the Earth.

In this video we'll write the correct name for N2. N2 is a diatomic molecule most commonly called Nitrogen gas . It can also be called Diatomic Nitrogen and Molecular Nitrogen . The seven...

Mar 26, 2025 · On a small scale, pure nitrogen is made by heating barium azide, Ba (N 3) 2. Various laboratory reactions that yield nitrogen include heating ammonium nitrite (NH 4 NO 2) solutions, oxidation of ammonia by bromine water, and oxidation of ammonia by hot cupric oxide.
