On Saturn's moon Titan, where the average surface temperature is −179 ∘C-179\text{ }^\circ\text{C}−179 ∘C, nitrogen (N2N_2N2) exists as a gas. Nitrogen is a simple molecular, covalent substance with a very low boiling point of −195.8 ∘C-195.8\text{ }^\circ\text{C}−195.8 ∘C.
Explain, in terms of structure and bonding, why nitrogen has a low boiling point.
