👉 Crystal is a type of solid that forms when two or more atoms are arranged in a regular pattern. These patterns can be found in various materials, including metals, semiconductors, and polymers. Crystal structures are characterized by their specific arrangement of atoms, which allows for the formation of different types of materials such as glass, ceramics, and alloys. Crystal has a unique property called its reciprocal lattice structure, which means that all atoms in a crystal follow the same periodic table-like arrangement. This
