What is the Formula for Nitrogen gas

There is the formula of nitrogen gas and their uses

Nitrogen gas

Nitrogen is a colorless, odorless, and the tasteless non-metallic element of the fifteenth group, referred to as N2, and has atomic number 7, the most abundant element in the Earth’s atmosphere, with four-fifths of its atmosphere. In addition, it is the sixth element in the global abundance, and nitrogen gas in the atmosphere is the main source of business and industry.

Also found in the envelope in the form of small amounts of ammonium salts, ammonia, nitric acid, and nitrogen oxides, and found free nitrogen In a number of meteorites Lise: meteorites), and in mines, volcanoes and some mineral springs gases, and in some of the stars and nebulae (in English: nebulae), and in the sun as well.

The formula of nitrogen gas


the formula of N2 gas is:

Symbol: N2
Atomic mass: 14.0067 u
Atomic number: 7
Electron configuration: [He] 2s22p3
Electronegativity: 3.04

Information on nitrogen gas

  • This gas is known to be tasteless, colorless and odorless, the atomic number of N2 gas is 7, and nitrogen gas is known to be one of the inactive gases that have five electrons inside the atmosphere.
  • This gas is known to be a gas that is difficult to dissolve with water. It also does not ignite and cannot interact with gases or other elements. It is a group of non-metallic gases.
  • This gas occupies the largest proportion of gases in the atmosphere, it is available by 78%, the doctor, “Rutherford,” a Scottish doctor who discovered hydrogen gas in the air.

The importance of nitrogen gas

The biological role of nitrogen

This gas plays a vital role. It is the element found in all living organisms and is a component of amino acids, that is, it is involved in the formation of proteins and nucleic acids, and is the component of almost all neurotransmitters, the main component of alkalis, and N2 is recycled through life naturally in what is known as the cycle of nitrogen.

As plants and algae get it in the form of nitrate, while the animals get it through other organisms consumption, containing in its constituent proteins and nucleic acids, as the transformation of microbes which Price nitrogen compounds to nitrate again to use, in addition to the bacteria nitrogen-fixing renewed supply of nitrate which directly from the atmosphere.

Nitrogen in industry

This is used in many industries, including the following:

  • This gas is used in food packaging as an alternative to oxygen, making the food last longer, and can also be used as a lining around food to protect it from damage in transport.
  • This gas is used to weld electronics.
  • This enters the stainless steel industry by using N2 as its coating, producing stronger corrosion-resistant steels.
  • This gas can be used to rid liquids of volatile organic compounds in them before disposal, reducing pollution.
  • This gas is used to make light bulbs, as it is a less expensive alternative to argon in incandescent lamps.
  • This is used to extinguish potential fires in mining by disposing of oxygen in the air.
  • It is also used to ensure that the area does not explode if it is neglected, as well as to prevent explosions in high-risk locations such as manufacturing facilities and chemical facilities.
  • This gas is useful for blowing tires, giving them a longer life by reducing oxidation, and improving the pressure of the gas trapped there.
  • This gas is introduced into the petroleum industry.
  • It is used to dispose of gases in large reservoirs to prepare it for storing oil.
  • It does not react with existing oil being idle.
  • This gas is used in the manufacture of various materials such as rubber, and plastics.
  • Pharmaceutical companies need high-quality refined nitrogen gas to be used to store and form medical compounds.
  • Dried, pressurized this gas is an insulator for high-voltage equipment and is used to drive liquids through pipes.
  • This gas is one of the most critical components of fertilizers used to increase soil fertility and is used to manufacture various types of fertilizers such as ammonia and urea.
  • This gas is used in the manufacture of explosive components such as dynamite and is used to form a wide range of highly reactive, unstable compounds of ammonium nitrate, nitrogen triiodide, nitric acid, and nitroglycerin.

Facts of N2 gas

There are several facts related to N2, including:

  • This gas has an atomic weight of 14.0067. The state of N2 at room temperature is invasive.
  • This gas was discovered by chemist and physician Daniel Rutherford in 1772. The boiling point of N2 is -195.79 degrees Celsius, while the melting point is 210 degrees Celsius.
  • The number of isotopes of N2 is sixteen, two of which are stable.
  • Oxygen gas plays a role in the formation of the aurora borealis, according to NASA, which occurs mostly in the north and south poles in the form of a natural view of light in the sky, as a result of the collision of fast-moving electrons, coming from space with this gas and oxygen in the atmosphere.
  • Liquid N2 is widely used as a coolant, such as sperm and egg storage, as well as many cells used in fertility clinics or medical research.
  • This gas can be produced by heating an aqueous solution of ammonium nitrate (NH4NO3), which is often used in fertilizers.
  • This makes up 95% of the atmosphere of Titan, Saturn’s largest moon.
  • According to the Royal Society of Chemistry, N2 was produced in the form of ammonium chloride NH4Cl by heating the mixture of urine, salt, and animal waste in ancient Egypt.
  • Fractional distillation of liquefied air is the basis of commercial N2 production, which can also be largely produced by burning carbon, or hydrocarbons, and separating water and carbon dioxide products from residual N2. Tight as its production by heating barium azide.
  • Nitrogen oxides are a group of seven gases and compounds composed of oxygen and nitrogen.
  • Nitric oxide and nitrogen dioxide are the most dangerous and common.
  • Nitrogen oxides are emitted from many sources such as burning coal, car exhaust, diesel fuel, natural gas, and so on.
  • Exposure to very high levels of these oxides can pose a significant risk to human health such as convulsions, genetic mutations, and increased speed. Pulse, you may reach death.

Is nitrogen gas flammable

Many scientists have conducted a lot of scientific experiments on nitrogen gas, it was discovered that nitrogen gas is a gas that does not ignite, and this is the result of many scientific experiments.

Nitrogen gas is an inert gas, which is known to be an inert gas that does not work and does not cause ignition and is also used to reduce the ignition caused by many other gases.

N2 gas damage

We all know the importance of nitrogen gas to humans, it is one of the gases necessary to complete life, but many scientists stressed that the gas nitrogen a lot of damage caused to humans, and the most important of these damages are

  • When nitrogen gas is released very quickly, suffocation occurs, because at that time it causes the complete elimination of the oxygen gas in place.
  • When nitrogen gas is inhaled by partial pressure, it causes a state of anesthesia for the injured, causing a person to faint.
  • When divers use the air so they can dive into the sea, especially if they are diving too deep to the seafloor, when the diver ascends to the surface, nitrogen gas with many cases causes low blood.
