Formula of Nitrogen (N2)
Identification of Nitrogen Chemical Compound
| Chemical Formula | N2 |
|---|---|
| Molecular Weight | 28.0134 g/mol |

Chemical Formula Description
The Nitrogen molecule contains a total of 2 atom(s). There are 2 Nitrogen atom(s). A chemical formula of Nitrogen can therefore be written as:
N2
The chemical formula of Nitrogen shown above is based on the molecular formula indicating the numbers of each type of atom in a molecule without structural information, which is different from the empirical formula which provides the numerical proportions of atoms of each type.
The above chemical formula is the basis of stoichiometry in chemical equations, i.e., the calculation of relative quantities of reactants and products in chemical reactions. The law of conservation of mass dictates that the quantity of each element given in the chemical formula does not change in a chemical reaction. Thus, each side of the chemical equation must represent the same quantity of any particular element based on the chemical formula.

Structure Data File (SDF/MOL File) of Nitrogen
The structure data file (SDF/MOL File) of Nitrogen is available for download in the SDF page of Nitrogen providing the information about the atoms, bonds, connectivity and coordinates of Nitrogen, which is not completely available in the chemical formula representation. The Nitrogen structure data file can be imported to most of the cheminformatics software for further analysis and visualization.
-
Chemical structure of Nitrogen
The chemical structure image of Nitrogen is available in chemical structure page of Nitrogen, which specifies the molecular geometry, i.e., the spatial arrangement of atoms in the chemical formula of Nitrogen and the chemical bonds that hold the atoms together.
-
Molecular weight of Nitrogen
The molecular weight of Nitrogen is available in molecular weight page of Nitrogen, which is calculated as the sum of the atomic weights of each constituent element multiplied by the number of atoms of that element specified in the chemical formula of Nitrogen.
-
InChI (IUPAC International Chemical Identifier) information of Nitrogen
The molecular chemical formulas lack structural information. An alternative textual expression including the structural information is InChI. The full standard InChI of Nitrogen is:
InChI=1S/N2/c1-2
It can provide a standard way to encode the molecular information of Nitrogen to facilitate the search for the compound information in databases and on the web.
The condensed, 27 character standard InChIKey (hashed version of the full standard InChI) of Nitrogen is:
InChIKey=IJGRMHOSHXDMSA-UHFFFAOYSA-N
The InChIKey may allow easier web searches for Nitrogen, but it needs to be linked to the full InChI to get back to the original structure of the Nitrogen since the full standard InChI cannot be reconstructed from the InChIKey.
