The lattice arrangement continues in three dimensions. This is why solid ionic compounds form crystals with regular shapes.

The decisive factor is often the arrangement of the molecules in the atomic lattice structure or on the surface of the ... says Oliver Hofmann from the Institute of Solid State Physics, who heads the ...

form a regular lattice structure in which oppositely charged ions are strongly attracted to each other. Sodium chloride is an ionic compound. The table shows some limitations of different models ...
