Invisible roommate
About 78% of dry air consists of molecular nitrogen N₂. We breathe it all the time, but oxygen steals all the glory.
A molecule with a big personality
The coolest gas in the room is invisible.
Meet Nitrogen: All around us, essential to life and so quiet that most substances can barely get it into conversation.
78% air
N₂ two atoms, one team

Big facts.
Little drama.
A quick introduction to an item that deserves more attention than it usually gets in the air.
🤝
Two atoms, strong bond
Atoms in N₂ are connected by a very strong triple bond. The molecule is therefore relatively unreactive under normal conditions.
🧬
Nitrogen is also in you
It is part of amino acids, proteins and building blocks of DNA and RNA. Without him, life would be pretty poorly written.
Fun fact no. 01
Nitrogen is everywhere.
But it is pretending that he does not exist.
It is used in industry as a protective atmosphere. Due to its extremely low boiling point, liquid nitrogen helps with rapid cooling and freezing.

PREMIUM DOMAIN · FOR SERIOUS OFFERS
Do you have an idea for n2.si?
n2.si is a premium domain, so we expect a very high offer. If there are more zeros in your phone number than in the offer, the calculator will probably replace the offer with a demonstration of the "0" key. Let the amount be such that the calculator checks for a moment whether it can still count. We do not consider or respond to low bids. You must answer both questions below correctly before submitting an offer. Only then will the English form appear.
