In crystallography, the crystal structure is how the atoms (or ions or molecules) are arranged in a crystalline material. Crystals occur naturally from the way the chemical bonds of the atoms connect. Symmetric repeating patterns occur in 3-D space in the crystal.
The crystal structure of a chemical is the shape of the crystal at the molecular level. There are several shapes of crystals. Sodium chloride is a cube. Copper sulfate is triclinic. Most things, even metals, have crystal structures. Some crystals fit more atoms in them than others, and these crystals usually weigh more.
