Daniel Rutherforddiscoverer of nitrogen Nitrogen compounds have a very long history, ammonium chloride having been known to Herodotus. They were well known by the Middle Ages. Alchemists knew nitric acid as aqua fortis strong wateras well as other nitrogen compounds such as ammonium salts and nitrate salts.

The mixture of nitric and hydrochloric acids was known as aqua regia royal watercelebrated for its ability to dissolve goldthe king of metals. Nitrogen was also studied at about the same time by Carl Wilhelm Scheele[7] Henry Cavendish[8] and Joseph Priestley[9] who referred to it as burnt air or phlogisticated air.

InLord Rayleigh discovered that an electrical discharge in nitrogen gas produced "active nitrogen", a monatomic allotrope of nitrogen.

Natural sources originated either from biology or deposits of nitrates produced by atmospheric reactions. Nitrogen fixation by industrial processes like the Frank—Caro process — and Haber—Bosch process — eased this shortage of nitrogen compounds, to the extent that half of global food production see Applications now relies on synthetic nitrogen fertilisers.

The two colours show the phase or sign of the wave function in each region. From left to right: A nitrogen atom has seven electrons. In the ground state, they are arranged in the electron configuration 1s2 2s2 x2p1 y2p1 z.

It therefore has five valence electrons in the 2s and 2p orbitals, three of which the p-electrons are unpaired. It has one of the highest electronegativities among the elements 3.

Due to these very high figures, nitrogen has no simple cationic chemistry. The 2p subshell is very small and has a very similar radius to the 2s shell, facilitating orbital hybridisation. It also results in very large electrostatic forces of attraction between the nucleus and the valence electrons in the 2s and 2p shells, resulting in very high electronegativities.

Hypervalency is almost unknown in the 2p elements for the same reason, because the high electronegativity makes it difficult for a small nitrogen atom to be a central atom in an electron-rich three-center four-electron bond since it would tend to attract the electrons strongly to itself.

Although each period 2 element from lithium to nitrogen shows some similarities to the period 3 element in the next group from magnesium to sulfur known as the diagonal relationshipstheir degree drops off quite abruptly past the boron—silicon pair, so that the similarities of nitrogen to sulfur are mostly limited to sulfur nitride ring compounds when both elements are the only ones present.

Nitrogen resembles oxygen far more than it does carbon with its high electronegativity and concomitant capability for hydrogen bonding and the ability to form coordination complexes by donating its lone pairs of electrons.

This is not possible for its vertical neighbours; thus, the nitrogen oxidesnitritesnitratesnitro-nitroso - azo - and diazo -compounds, azidescyanatesthiocyanatesand imino -derivatives find no echo with phosphorus, arsenic, antimony, or bismuth.

By the same token, however, the complexity of the phosphorus oxoacids finds no echo with nitrogen. Orange indicates proton emission nuclides outside the proton drip line ; pink for positron emission inverse beta decay ; black for stable nuclides; blue for electron emission beta decay ; and violet for neutron emission nuclides outside the neutron drip line.

Proton number increases going up the vertical axis and neutron number going to the right on the horizontal axis. Nitrogen has two stable isotopes: The first is much more common, making up This leads to an atomic weight of around These reactions typically result in 15N enrichment of the substrate and depletion of the product.

The low natural abundance of 15N 0. As a result, the signal-to-noise ratio for 1H is about times as much as that for 15N at the same magnetic field strength. No other nitrogen isotopes are possible as they would fall outside the nuclear drip linesleaking out a proton or neutron.

It is produced from 16O in water via an n,p reaction in which the 16O atom captures a neutron and expels a proton.

It has a short half-life of about 7. There are five bonding orbitals and two antibonding orbitals marked with an asterisk; orbitals involving the inner 1s electrons not showngiving a total bond order of three.

Atomic nitrogen, also known as active nitrogen, is highly reactive, being a triradical with three unpaired electrons. Free nitrogen atoms easily react with most elements to form nitrides, and even when two free nitrogen atoms collide to produce an excited N2 molecule, they may release so much energy on collision with even such stable molecules as carbon dioxide and water to cause homolytic fission into radicals such as CO and O or OH and H.

Atomic nitrogen is prepared by passing an electric discharge through nitrogen gas at 0. This molecule is a colourless, odourless, and tasteless diamagnetic gas at standard conditions: Triple bonds have short bond lengths in this case, If they could be synthesised, they may have potential applications as materials with a very high energy density, that could be used as powerful propellants or explosives.

The opposite is true for the heavier pnictogens, which prefer polyatomic allotropes. This structure is similar to that of diamondand both have extremely strong covalent bondsresulting in its nickname "nitrogen diamond". It forms a significant dynamic surface coverage on Pluto [39] and outer moons of the Solar System such as Triton.

It is very weak and flows in the form of glaciers and on Triton geysers of nitrogen gas come from the polar ice cap region.Liquid nitrogen readily evaporates to form gaseous nitrogen, and hence the precautions associated with gaseous nitrogen also apply to liquid nitrogen.

For example, oxygen sensors are sometimes used as a safety precaution when working with liquid nitrogen to alert workers of gas spills into a confined space. Nitrogen is an important component of many important structural, genetic and metabolic compounds in plant cells. It’s a major element in chlorophyll, the compound by which plants use sunlight energy to produce sugars from water and carbon dioxide, or, in other words, photosynthesis.

systems. Transforming the highly mobile nitrate into nitrogen gas (denitrification) is the most difficult stage in the process and the step that adds the greatest complexity to the entire process. Because standard systems are inefficient in removing nitrate, additional treatment options need to be inserted into the treatment process.

Liquid nitrogen readily evaporates to form gaseous nitrogen, and hence the precautions associated with gaseous nitrogen also apply to liquid nitrogen. [97] [98] [99] For example, oxygen sensors are sometimes used as a safety precaution when working with liquid nitrogen to alert workers of .

Nitrogen is an element with the atomic symbol N, atomic number 7, and atomic weight [; ]. Nitrogen exists as a diatomic gas and makes up about 78% of the earth's atmosphere by volume. It is a constituent of proteins and nucleic acids and found in all living cells.

Argon was discovered as a result of trying to explain why the density of nitrogen extracted from air differed from that obtained by the decomposition of ammonia. Ramsay removed all the nitrogen from the gas he had extracted from air, and did this by reacting it with hot magnesium, forming the solid magnesium nitride.
