This is how molecules of a gas consense to form a solid, such as snow.
The different sized molecules form distinct bands on the gel.
There seems no doubt that molecules such as these could have formed in the seas of the earth at the very beginning of its history.
If the substance lacks the ability to dissolve in water the molecules form a precipitate.
There are also many examples of inorganic molecule forming rings.
These molecules can be used individually or en masse to form new kinds of materials.
In those domains, molecules had formed that could survive the more minor fluctuations of local conditions.
Some try to distinguish self-assembly as the process by which individual molecules form the defined aggregate.
Even if a molecule does not form a permanent dipole, it can still be influenced by an electric field.
The molecules of acids and bases form an equilibrium with their ions.
