Is nitrogen a solid liqued or gas at room temperature?
Nitrogen is a gas at room temperature. Nitrogen gas makes up 78% of the air in the atmosphere.
The reason for this lies in the atomicity of Nitrogen an phosphorous. Nitrogen exists as a diatomic molecule whereas phosphorous exists as P4 molecule. Therefore, the nature of interactions in phosphorous are stronger as compared to nitrogen and hence it has a higher melting point than Nitrogen and exists as solid at room temperature.
N2 - nitrogen gas - is gaseous at "room temperature". Nitrogen is about 80% of our atmosphere. K2S, potassium sulfide, is a solid. C8H18, or CH3(CH2)6CH3, is octane, a liquid component of gasoline. H2O is water, a liquid at room temperature. (Unless you are an Eskimo.) CaF2, Calcium Fluorate, is a solid called "fluorospar".
