Nitrogen compounds have a very long history, ammonium chloride having been known to Herodotus. They were … Näytä lisää

A nitrogen atom has seven electrons. In the ground state, they are arranged in the electron configuration 1s 2s 2p x2p y2p z. It, therefore, has five valence electrons in the 2s and 2p orbitals, three of which (the p-electrons… Näytä lisää

The first example of a dinitrogen complex to be discovered was [Ru(NH3)5(N2)] (see figure at right), and soon many other such complexes were discovered. These complexes, in which a nitrogen molecule donates a… Näytä lisää

Nitrogen is the most common pure element in the earth, making up 78.1% of the volume of the atmosphere (75.5% by mass), around 3.89 million gigatonnes. Despite this, it is not very abundant in Earth's crust, making u… Näytä lisää

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 generator… Näytä lisää

The applications of nitrogen compounds are naturally extremely widely varied due to the huge size of this class: hence, only applications of pure nitrogen itself will be considered here. Two-thirds (2/3) of nitrogen p… Näytä lisää
