Final answer:
The regular structure found in ionic compounds is called a giant crystal lattice, which is a three-dimensional geometric arrangement of ions.
Step-by-step explanation:
The regular structure found in ionic compounds is called a giant crystal lattice. This type of structure is characteristic of ionic substances, which consist of myriad ions bonded together into an extensive network. In a crystal lattice, ions are arranged in a regular.
Geometric pattern that extends in three dimensions throughout the material. Ionic compounds such as sodium chloride (NaCl) do not contain just one sodium and one chlorine ion; rather, they include a large number of each ion type, organized in the lattice where the ratio of sodium to chlorine ions is 1:1.
When considering ionic crystals, like that of CsCl, they often form a simple cubic structure. The crystal lattice of such a compound can be described using unit cells with cations at the corners and anions filling the other positions, or vice versa depending on the substance.
