Clusters in crystal patterns refer to the arrangement of atoms, ions, or molecules in a structured, repeating pattern that forms a crystal lattice. These clusters can vary in shape and size, influencing the properties of the material, such as its symmetry and stability. Common crystal patterns include cubic, tetragonal, orthorhombic, hexagonal, and rhombohedral structures, each characterized by specific geometric arrangements. Understanding these clusters is essential for fields like materials science, chemistry, and solid-state physics.
two types of star clusters are Open clusters and globular clusters

When a crystal grows in unrestricted space, growth occurs through the addition of atoms or molecules from the surrounding environment to the crystal lattice. This process typically involves nucleation, where clusters of atoms form stable structures, followed by the incorporation of additional particles that align with the existing lattice. The growth rate can be influenced by factors such as temperature, concentration of the growth species, and the presence of impurities or defects. Ultimately, this leads to the expansion of the crystal in a structured and organized manner.
A career cluster is a group of jobs and industries that are related by skills or products. There are 16 clusters established by the States' Career Clusters and are recognized by the USA.
Clusters of stars that all appear to lie at the same distance from us are called star clusters. There are two main types: open clusters, which contain young stars and are loosely bound together, and globular clusters, which contain older stars and are tightly packed.
Patterns in Waterford Crystal are traditionally cut by hand. However, much Waterford crystal is now produced outside the Republic of Ireland, typically in Eastern Europe.
When ions arrange themselves into orderly patterns, it is called crystallization. This process involves the ions coming together in a structured arrangement to form a crystal lattice, leading to the formation of a solid crystal.
The repeating patterns of a mineral's particles that form a solid are called crystal lattice structures. These structures are responsible for the characteristic shape and properties of minerals.
Cleavage surfaces will be smooth, flat, and exhibit specific patterns of breakage, depending on the mineral's cleavage plane. Crystal surfaces, on the other hand, will display the crystal shape and characteristic geometric patterns unique to that mineral. Crystal surfaces can also sometimes show growth lines or striations indicating the crystal's formation process.
A crystal lattice is formed when molecules or atoms arrange themselves in repeating patterns. This regular arrangement leads to the formation of a crystal structure with specific geometric properties.

Ionic bonds form the same crystal patterns because they involve strong electrostatic attractions between oppositely charged ions. This arrangement allows for the maximum packing efficiency of ions in a crystal lattice, leading to predictable and repeating patterns in the structure. The specific arrangement of ions in an ionic crystal is determined by the relative sizes and charges of the ions involved.
The crystal structure of a material can be determined using techniques such as X-ray crystallography, electron diffraction, and neutron diffraction. These methods involve analyzing the diffraction patterns produced when a beam of X-rays, electrons, or neutrons interacts with the crystal lattice of the material. By interpreting these patterns, scientists can determine the arrangement of atoms within the crystal structure.
Fifty to eighty percent of the epileptic spasms occur in clusters of two to more than 100 seizures. Patients may have dozens of clusters and several hundred spasms per day
The clusters on a fern leaf, known as sori, contain sporangia which produce spores. These sporangia are typically located on the undersides of the leaves and can be arranged in various patterns. The spores are released when mature, allowing the fern to reproduce and disperse.
