In mineralogy and crystallography, a crystal structure<span> is a unique </span>arrangement of atoms<span> in a </span>crystal. Atomic arrangement of atoms in this kind of structure usually very symmetrical and highly ordered. Causing the component within the structure is so strong and hard to break. <span>A </span>crystal structure<span> is composed of a unit cell, a set of </span>atoms arranged<span> in a particular way; which is periodically repeated in three dimensions on a lattice. </span>Crystal structure would be commonly found in solid compounds.
