WebElements Periodic Table » Nitrogen » historical information

Nitrogen was discovered by Daniel Rutherford in 1772, who called it noxious air, but Scheele, Cavendish, Priestley, and others at about the same time studied "burnt" or "dephlogisticated" air, as air without oxygen was then called.

History. About four-fifths of Earth’s atmosphere is nitrogen, which was isolated and recognized as a specific substance during early investigations of the air. Carl Wilhelm Scheele, a Swedish chemist, showed in 1772 that air is a mixture of two gases, one of which he called “fire air,” because it supported combustion, and the other “foul air,” because it was left after the “fire ...

Nitrogen - Wikipedia

Nitrogen gas is an industrial gas produced by the fractional distillation of liquid air, or by mechanical means using gaseous air (pressurised reverse osmosis membrane or pressure swing adsorption). Nitrogen gas generators using membranes or pressure swing adsorption (PSA) are typically more cost and energy efficient than bulk delivered nitrogen.

Nitrogen And Cannabis • Soft Secrets

When growing cannabis, we are all aware that the three main nutrients a plant needs is Nitrogen, Phosphorus and Potassium. Accompanied by a group of micro and macro nutrients, the photo tropical plant is able to fulfil its task of growing perfect leaves, stems and cannabis buds. However, there are stages throughout the plant's life that the requirement of these fundamental elements will change.

Nitrogen is the seventh most abundant element in the Milky Way, and like many elements it is formed as a residue from an exploding star. The problem is that most nitrogen atoms are tightly bonded with other nitrogen atoms using three of its seven electrons, creating what is known in chemistry as a powerful triple bond (N≡N).

Rob, if you poke around on the internet you can find many sites that show diagrams for how the $\ce{N2}$ molecular orbitals are formed from two sets of nitrogen ($\ce{N1}$) atomic orbitals. Many of the diagrams are different one from another - that's a tip off that s-p mixing is not something that can always be predicted in advance.

Why is it difficult to mix helium and nitrogen gases?

I recently learned an interesting fact: That it's difficult to mix helium and nitrogen gases in a compressed gas cylinder. Gas suppliers that need to mix the two gases have to rotate the cylinders for hours or even days after the two gases are injected to get the two gases to mix. And once they are mixed they do not separate again.
