Media, glossary, and source library
This library gathers useful starting points. Topic pages link sources that support their claims; this page is a map, not a substitute for checking original material.
A tiny glossary
Atom: the smallest unit of an element. Molecule: bonded atoms. N₂: molecular nitrogen. Fixation: conversion of N₂ into usable forms. Nitrate: NO₃⁻. Ammonium: NH₄⁺. Isotope: atoms with different neutron counts.
Check sources and media
Prefer primary data, government agencies, universities, standards bodies, and peer-reviewed research. Check dates, units, and whether a source concerns N₂ or a different compound. External video stays hosted by its owner; reuse needs permission checks.
Sources and further reading
These references are starting points. Check the source directly for definitions, dates, units, and context. This is an educational overview, not an operating manual or professional advice.
Have a big idea for n2.si?
We expect a substantial offer; low bids will not be considered or answered. Answer two quick questions on the home page to open the English offer form.
A premium offer should be better sourced than a rumor in the chemistry corridor.
