Crystal Lattice

A crystal lattice is a repeating three-dimensional pattern of atoms, ions, or molecules in a solid crystal. This regular arrangement gives crystals their unique structure and properties. The crystal lattice can be thought of as a framework that extends throughout the entire crystal, holding the atoms or molecules in place.

In a crystal lattice, each particle is located at specific positions relative to its neighboring particles. The arrangement of these particles can be represented by a unit cell, which is the smallest repeating unit of the lattice. The shape and size of the unit cell determine the overall structure of the crystal lattice.

Crystals can have different types of lattice structures, such as cubic, hexagonal, tetragonal, orthorhombic, monoclinic, and triclinic, based on the arrangement of the unit cells.
