Nitrogen (N) has the atomic number 7 on the periodic table and is mostly found in the colorless, gaseous form. Nitrogen is also the most abundant element on the planet Earth.

Is nitrogen electropositive?

Ammonia - NH3 - when mixed with water is represented as NH4+; so, therefore, yes.

Atmospheric Sciences

What are the uses of the nitrogen that composes 79 percent of the Earth's atmosphere?

Nitrogen occurs as a diatomic gas in the atmosphere. It is usually not that reactive because two nitrogen atoms are bonded together by triple bonds. Liquid nitrogen has varied uses. For example getting extremely temperatures, magnetic levitation, in the filed of medicine etc.


When do you we use nitrogen?

mostly, nitrogen is used when there is an inert gas needed but oxygen wouldn't work very well. some applications are: to keep bulk foods fresh, in incandescent bulbs as a cheap alternative to argon, the production of electronic parts, in electrical equipment, manufacturing of stainless steel, military aircraft fuel systems to reduce fire hazard, on top of liquid explosives as a safety measure, inside tires (sometimes), and a propellant for wine, and im pretty sure that's whats in those spray cans of air, and whipcream gas. btw the guy that said u make explosives out of it to blow up the U.S. was wrong.


Is nitrogen dioxide more dangerous than nitrogen?

Yes nitrogen dioxide is more dangerous than nitrogen as it readily forms more complex compounds which are hazardous including strong acids when mixed with water.


Is nitrogen inflammable?

Nitrogen is an inert gas, which means that it will not ignite using conventional means.

What are the abiotic components of the nitrogen cycle?

There are currently a large number of well-characterized, ischemic stroke animal models available for pre-clinical research. For stroke studies, Acroscell provides studies for neuroprotection and reduction of infarct, as well as longer-term, more comprehensive studies looking at functional and cognitive outcomes or stroke prevention. In Acroscell, all studies can be customized and adjusted to meet client needs.


What is nitrogen cellulose?

low melting gas, usually used in gun.


What are the uses for nitrogen?

  • The main use of Nitrogen by man is to make fertilizers.
  • It is also used to make nitrous oxide (laughing gas), an anesthetic agent often used in the dentist office and other health care settings.
  • It can be used to make plastics, explosives, rocket fuel, and ammonia.
  • It is used in the manufacture of light bulbs, light bulbs are almost always filled with Nitrogen.
  • Liquid nitrogen is extremely cold and can be used to cool things, or to instantly freeze them in scientific experiments and other uses that require very low freezing temperatures like freeze drying.
  • 78.1% of the air one breathes is nitrogen.
  • Nitrogen can be used in the processing of iron and steel, for example, a blanket of nitrogen placed above the metals prevents their reacting with oxygen.
  • Biochemically, nitrogen is used to construct proteins.
Nitrogen has two very large areas of use:

Nitrogen is the basis for most explosives. Trinitrotoluene (TNT) is a toluene molecule with three NO2 groups attached. Nitroglycerin is a glycerin molecule with three NO2 groups attached. Dynamite is nitroglycerin absorbed by wood pulp. Plastic explosives are mainly rings with three NO2 groups. PETN, a very powerful explosive has four (tetra) NO2 groups.

Nitrogen's other major use is life. Everything that grows needs nitrogen. It must be supplied to crops by some manner, such as fertilization, and to animals and people by their food. It is a component of amino acids, thus of proteins, of RNA and of DNA.

Nitrogen is a component of air: 80% nitrogen, 20 % oxygen, a little CO2, some water vapor, and other assorted gases.


What is the balanced equation for nitrogen plus hydrogen -- nitrogen trihydride?

N2 + 3H2 yields 2NH3. NH3 is also called ammonia.

Earth Sciences

What is nitrogen fixation?

Nitrogen fixation is the process of nitrogen gas from the air being turned into a compound in the soil by bacteria that live in the root nodules of certain plants (legumes).

Nitrogen gas makes up 78% of our atmosphere and nitrogen is also a part of many molecules essential to life like proteins, nucleic acid and some vitamins. Nitrogen is found in other biologically important compounds such as alkaloids and urea too. Nitrogen is thus an essential nutrient for all lifeforms could use atmospheric nitrogen directly.

Nitrogen fixation is the natural process by which atmospheric nitrogen (N2) is converted into ammonia (NH3), or nitrate forms. This step is important for the continuation of ecosystems because plants depend on nitrates and nitrites, and nitrogen gas is not a usable form for plants to intake. Nitrogen fixation is typically carried out by rhizomes, legumes, and other nitrogen-fixing organisms; these organisms usually have a symbiotic relationship with plants. The formula for nitrogen fixation is like this:

N2 + 8 H+ + 6 e� � 2 NH3 + H2

Two processes in which atmospheric or dissolved nitrogen is converted into nitrate ions; part of the nitrogen cycle; both lightning and some soil bacteria can fix niterogen.

What is the role of nitrogen-fixing bacteria in the nitrogen cycle?

Although the air is made up of about 70% nitrogen, plants cannot use nitrogen in this N2 form. Nitrogen fixing bacteria change nitrogen into the form of soluble nitrates so that plants can use it. Other bacteria, known as de-nitrifying bacteria, change nitrates back into N2, which completes the nitrogen cycle

How dangerous is nitrogen?

It is NOT.

non-toxic, non-explosive, non-reactive, non-corrosive: almost completely INERT.

However, if you breath pure nitrogen gas you asphyxiate and die because there is no oxygen.

However, don't stick your fingers in liquid nitrogen, they'll be 'burned' at -190oC.


How was nitrogen named?

why was nitrogen named nitrogen


What are methods of nitrogen fixation that complete the nitrogen cycle?

nitrogen fixation takes place with the help of lightning , bacteria called rhizobium lives in the nodules of legumenous plants convert nitrogen into nitrogeous compounds , algae etc. also helps in nitrogen fixation


Is nitrogen brittle?

Brittleness is a concept applied to solids. Solid nitrogen appears under extremely high pressures and low temperatures. The structure is like diamond, and probably as hard. So probably it is brittle.

History of Science

Who discovered nitrogen?

Nitrogen was isolated by the British physician Daniel Rutherford in 1772, but was not recognized as an element until 1776 by the French chemist Antoine Laurent Lavoisier.


What is the melting point of nitrogen?

Nitrogen, which is an atmospheric gas (and the most common one) melts at 63.153 Kelvin , -210.00 ° Celsius, -346.00 ° Fahrenheit.

What are the number of moles of nitrogen atoms in 56g nitrogen gas?


Elements and Compounds

What is the importance of nitrogen fixation?

Plants need nitrogen in order to grow. Nitrogen is abundant in the earth's atmosphere, but plants cannot use it in that particular form (nitrogen gas). Certain bacteria which reside on some plant roots are able to change atmospheric nitrogen into a form that plants can use (ammonia).


What charge does nitrogen have?

Elemental nitrogen has no charge.

In ammonia (NH3) and ammonium ions (NH4+) it has a oxidation value of -3 (and actually only a partial negative charge as part from a polar covalent, non-ionic bond).

In Nitrate (NO3-) its oxidation value is +5, in nitrite +3 (but only a partial positve charge in both)


Where is nitrogen found?

Nitrogen can be found and obtained from air. about 78.08% of the air we breathe is nitrogen...
Nitrogen is a gas.It is dominant in atmosphere.


What is nitrogen?

Nitrogen is a gas. It cannot be broken down because it is a element. Daniel Rutherford discovered nitrogen. At frist nitrogen is called free nitrogen but when it goes through nitrogen fixation it can be useable.


How nitrogen fixation by symbiotic nitrogen fixers?
