Unit cell
A unit cell is the smallest repeating unit of a solid crystal that shows the entire structure of that crystal when repeated in three-dimensional space. Think of it like a building block: just as a small brick can form a large wall when stacked together, a unit cell can create the entire crystal by being repeated in various directions. Each unit cell has specific dimensions and angles that define the crystal's overall shape and properties, making it fundamental in fields like chemistry and materials science for understanding how solids are organized and behave.

A unit cell is the smallest repeating unit in a crystal lattice structure that defines the arrangement of atoms within a crystal. It serves as a building block, depicting the geometric shape and symmetry of the entire crystal. Just like a single tile can represent the overall pattern of a tiled floor, a unit cell reflects how atoms are organized in three-dimensional space. By repeating this unit in various directions, a complete crystal structure is formed, influencing the material's properties such as strength, conductivity, and appearance.
