What is n2 used for?
Nitrogen (N2) is a colorless, odorless and tasteless gas that makes up 78.09% (by volume) of the air we breathe. It is commonly thought of and used as an inert gas; but it is not truly inert. It forms nitric oxide and nitrogen dioxide with oxygen, ammonia with hydrogen, and nitrogen sulfide with sulfur.
Nitrogen group element. Nitrogen group element, any of the chemical elements that constitute Group 15 (Va) of the periodic table. The group consists of nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), bismuth (Bi), and moscovium (Mc).
Nitrogen is a colorless, odorless, tasteless, diatomic and generally inert gas at standard temperature and pressure. At atmospheric pressure, nitrogen is liquid between 63 K and 77 K.
Definition of nitrogen. : a colorless tasteless odorless element that as a diatomic gas is relatively inert and constitutes 78 percent of the atmosphere and that is a constituent of organic compounds found in all living tissues — see Chemical Elements Table. —
This group is also known as the nitrogen family. It consists of the elements nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), bismuth (Bi), and perhaps the chemically uncharacterized synthetic element moscovium (Mc). In modern IUPAC notation, it is called Group 15.
Nitrogen. Chemical Names: Nitrogen; Nitrogen gas; Molecular nitrogen; 7727-37-9; Nitrogen-14; Dinitrogen More
Oxygen is denser than both air and nitrogen, at all temperatures and pressures, but only slightly. Since they don't separate from each other, we generally don't worry which is lighter or heavier. The difference in the density of nitrogen and oxygen gas comes from their molecular weight, which is small (4 g/mol).
Nitrogen (N2) is a colorless, odorless and tasteless gas that makes up 78.09% (by volume) of the air we breathe. It is nonflammable and it will not support combustion. Nitrogen gas is slightly lighter than air and slightly soluble in water. It is commonly thought of and used as an inert gas; but it is not truly inert.

N2 is the formula of the nitrogen molecule, which has two atoms of nitrogen in it.. The nitrogen gas exists only as N2 molecules in free state. Nitrogen will bond so it can form a stable octet ( 8 outer electrons) so it forms three bonds as it is in group 5, we know that nitrogen has 5 valence (outer) electrons.
Nitrogen itself is an element. But nitrogen is found as N2 in nature. A compound is a molecule that contains at least two different elements (i.e. water) while a molecule is formed when two or more atoms join chemically. All compounds are molecules but not all molecules are compounds.
The nonmetal elements occupy the upper right-hand corner of the periodic table. The nonmetal element group is a subset of these elements. The nonmetal element group consists of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur and selenium.
Nitrogen is present as N2 or dinitrogen. The two atoms of nitrogen are attached by a triple bond between them which is very strong. To break such a strong energy bond tremendous energy is needed which is not available in inert conditions. That is why nitrogen is inert in room temperature.
Air is mostly nitrogen, which is not flammable. Nitrogen is also non-reactive in general, so it doesn't support the combustion of other materials, either. After nitrogen, the most abundant gas in our air is oxygen.
Nitrogen was named by French chemist Jean-Antoine Chaptal in 1790. He named it after the mineral niter when he found that niter contained the gas. Niter is also called saltpeter or potassium nitrate.
The non-metals or non-metallic elements; hydrogen (H), carbon (C), nitrogen (N), oxygen (O), phosphorus (P), sulphur (sulfer) (S), selenium (Se), (Uuo may belong here) and the noble gases form a relatively small group with a step like pattern towards the left-hand side of the periodic table (hydrogen being the odd one
Atomic mass of Nitrogen element is 14.0067 amu. Nitrogen molecule is N2, so molecular mass of nitrogen molecule is 2*14.0067 = 28.013. This means, every one mole of nitrogen gas weighs 28.013 grams and contains 602 hexillion molecules of N2.
Because 78 percent of the air we breathe is nitrogen gas, many people assume that nitrogen is not harmful. However, nitrogen is safe to breathe only when mixed with the appropriate amount of oxygen. These two gases cannot be detected by the sense of smell.
Nitrogen was discovered by the Scottish physician Daniel Rutherford in 1772. It is the fifth most abundant element in the universe and makes up about 78% of the earth's atmosphere, which contains an estimated 4,000 trillion tons of the gas.
Nitrogen is a component of chlorophyll and therefore essential for photosynthesis. It is also the basic element of plant and animal proteins, including the genetic material DNA and RNA, and is important in periods of rapid growth. Plants use nitrogen by absorbing either nitrate or ammonium ions through the roots.
They contain symbiotic bacteria called rhizobia within nodules in their root systems, producing nitrogen compounds that help the plant to grow and compete with other plants. When the plant dies, the fixed nitrogen is released, making it available to other plants; this helps to fertilize the soil.
