Lattice - GCSE Chemistry Definition

In GCSE Chemistry, a lattice is a regular, repeating structure that shows how atoms, ions, or molecules are arranged in a solid. Imagine a lattice as a three-dimensional grid where the particles are packed closely together in a set pattern. This structure is important because it affects the properties of the substance, like how hard or brittle it is and how it conducts electricity. Common examples of lattices include the arrangement of ions in a salt crystal or the network of carbon atoms in a diamond. Understanding lattices helps us learn why different materials behave the way they do.
