Nitrogen comprises 78% of the atmosphere while oxygen comprises 21%. Those two gases have low boiling points and therefore can exist as gases under normal environmental conditions. How can the intermolecular forces that exist between the nitrogen molecul

Nitrogen (N2) and Oxygen (O2) are non polar molecules and therefore the intermolecular force between is the weakest, which is the dispersion force. The low boiling point is due to this force between the molecules which causes the bond to be easily broken.
