Giant Ionic Lattice - GCSE Chemistry Definition

A giant ionic lattice is a three-dimensional structure that is large and is composed of numerous ions that are held together by strong ionic bonds. These bonds form between positively and negatively charged ions, which attract each other like magnets. This structure is found in substances such as sodium chloride (table salt) and gives these compounds their unique properties, like high melting and boiling points, and the ability to conduct electricity when dissolved in water or melted. The regular arrangement of ions means that each ion is surrounded by ions of the opposite charge, creating a repeating pattern that extends in all directions throughout the solid.
