Crystalline solids are usually molecules or ionic structures that create a lattice. One such example of an ionic lattice is salt (NaCl) where the positive sodium ions are attracted to the negative chloride ions. An example of a polar molecular lattice is glucose. One part of the molecule has a greater electronegativity than the rest, and bonds adhering to that pattern to other molecules on their less electronegative portions. Iodine is an example of a molecular lattice. It is bound by van der Waals forces.

These are solids where enough of the particles are arranged in regular patterns for that order to be reflected in the shape of the visible grains. Table sugar and salt are obvious examples. If the particles are arranged very randomly, we say the solid is amorphous. An example of this would be soot.
