Question

Do molecules in the solid state arrange themselves into a crystal lattice?

Answer 1

Yes, most molecules in the solid state arrange themselves into a crystal lattice.

Explanation:

A lattice is a regular arrangement of particles, and these can be atoms, ions, or molecules.

Perhaps the most common molecule with a crystal lattice is water.

Water molecules arrange themselves into an open array that is responsible for the unusual density of ice.

Iodine molecules solidify into a lattice.

Even Dry Ice (solid carbon dioxide) forms a crystal lattice.

The list goes on.
