Nitrogen / N₂

We have been aware of compounds containing nitrogen, such as potassium nitrate, since antiquity, but the isolation of this element is attributed to Rutherford in 1772, and was achieved independently by Cavendish and Scheele.
Nitrogen is a diatomic molecule comprising two nitrogen atoms. Under normal temperature and pressure conditions, nitrogen molecules form a colourless gas, which makes up 78% of air. Now, as it is the main component of air with a concentration of 78.06% in volume and 75.5% in mass, nitrogen is generally obtained by converting air to liquid, followed by fractional distillation.
It is a colourless and odourless gas, and in liquid form it is extremely cold, colourless and odourless.
