Nitrogen gas makes up about 80% of the air we breathe. is necessary for many biological processes and is used as a fertilizer in the form of ammonia or ammonia-based compounds, and the compounds formed with halogens and certain organic compounds can be explosive. it is an unreactive gas. This is the basis of the ‘ideal gas’ approximation, of which more later. Nitrogen exists as a diatomic molecule while phosphorus and other elements of the group exist as tetratomic molecules. 3. It is non-metal diatomic gas with an electronegativity of 3.0. The physical state of a pure gas (as opposed to a mixture) may be defined by four physical properties: p – the pressure of the gas T – the temperature of the gas V – the volume of the gas n – the number of moles of substance present The element exists as N2 molecules, represented as :N:::N:, for which the bond energy of 226 kilocalories per mole is exceeded only by that of carbon monoxide, 256 kilocalories per mole.
