Intermolecular forces
In case of ionic bonds, the ions are in an ionic lattice.
In case of a metalic bond, there is a metalic lattice for the participating particles.
How about molecules?
Inside molecules there are intramolecular forces: the covalent bonds.
But, there are also forces between the molecules, called: intermolecular forces.
e.g.: vanderwaals forces, polar forces, hydrogen bridges.
