Solids with particles arranged in repeated three-dimensional patterns are called crystalline solids.

Here's why:

* Crystalline refers to the specific structure of the solid.

* Solid implies that the particles are tightly packed and have a fixed shape.

Examples of crystalline solids include:

* Salt (NaCl): The sodium and chloride ions form a repeating cubic structure.

* Diamonds (Carbon): Carbon atoms are arranged in a strong, rigid tetrahedral structure.

* Quartz (SiO2): Silicon and oxygen atoms form a complex, repeating structure.
