Nonliving, solid material formed in nature with particles arranged in a repeating pattern is a mineral. Atoms of a mineral are arranged in a repeating pattern to form a solid that is called a crystal.
Solids in which atoms are arranged in a definite and repeating pattern are called crystalline solids. In these solids, the atoms are arranged in a highly ordered structure, forming a crystal lattice. This arrangement gives crystalline solids their unique properties, such as cleavage and anisotropy.

A state of matter where particles are arranged in an ordered pattern and do not flow is called a solid. In a solid, particles are closely packed together and vibrate about fixed positions, giving the material a definite shape and volume.
That is called an asterism.(Note: The word "constellation" is also used, but actually, the current definition of "constellation" is unrelated to stars.)
To be classified as a mineral, a material must be naturally occurring, inorganic, and have a definite chemical composition. It should possess a crystalline structure, meaning its atoms are arranged in an orderly, repeating pattern. Additionally, minerals must be solid at room temperature and typically exhibit specific physical properties such as hardness, color, and luster.

Minerals form a special kind of solid called a crystalline solid. This means that the atoms within the mineral are arranged in a specific, repeating pattern that gives the mineral its unique structure and properties.
The repeating arrangement of atoms in a mineral forms a crystal due to the strong forces of attraction between the atoms, which result in a stable and orderly structure. This repeating pattern allows the mineral to grow in a geometrically regular shape, creating distinct crystal faces and external symmetry.
