Physical appearance A colourless, odourless fuel. Takes advantage of Nitrogen is significant towards the chemical marketplace. It is used to make fertilisers, nitric acid, nylon, dyes and explosives. To generate these products and solutions, nitrogen should 1st be reacted with hydrogen to generate ammonia. This really is completed with the Haber system. 150 million tonnes of ammonia are made in this manner annually.
Nitrogen can be usefully as compared to its horizontal neighbours carbon and oxygen as well as its vertical neighbours in the pnictogen column (phosphorus, arsenic, antimony, and bismuth). Even though Every time period 2 component from lithium to nitrogen displays some similarities for the time period 3 factor in the subsequent group from magnesium to sulfur (generally known as the diagonal associations), their degree drops off very abruptly previous the boron–silicon pair, so the similarities of nitrogen to sulfur are primarily limited to sulfur nitride ring compounds when the two aspects are the sole types current. Nitrogen resembles oxygen way over it does carbon with its large electronegativity and concomitant functionality for hydrogen bonding and the chance to type coordination complexes by donating its lone pairs of electrons. It does not share carbon's proclivity for catenation, Using the longest chain of nitrogen however found becoming composed of only eight nitrogen atoms (PhN=N–N(Ph)–N=N–N(Ph)–N=NPh).

Nitrogen trichloride (NCl3) is often a dense, risky, and explosive liquid whose Actual physical Attributes are just like People of carbon tetrachloride, Though 1 change is usually that NCl3 is easily hydrolysed by water though CCl4 will not be. It had been first synthesised in 1811 by Pierre Louis Dulong, who shed 3 fingers and an eye to its explosive tendencies. As a dilute fuel it really is less risky and is also Therefore made use of industrially to bleach and sterilise flour. Nitrogen tribromide (NBr3), 1st prepared in 1975, is often a deep crimson, temperature-sensitive, unstable sound that's explosive even at −a hundred °C.
Nitrous acid (HNO2) just isn't often called a pure compound, but is a common part in gaseous equilibria and is an important aqueous reagent: click here its aqueous answers may very well be created from acidifying interesting aqueous nitrite (NO−
