WebThe network solids have higher melting and boiling points because both metallic bonds and covalent bonds are very strong interactions. These strong interactions must be broken when the solid melts (or the liquid boils). It would require a lot of energy (high temperature) to break these interactions. LDFs are relatively weak interactions. WebAt this point, the energy of the two-hydrogen "system" is minimized, and the hydrogen molecule is stable. The distance between the nuclei (the bond length) in this case is 74 picometers, or 0.000000000074 meters.
