Ionic radius refers to the size of an ion in a crystal lattice, which can vary depending on the ion's charge and the coordination number. Cations are generally smaller than their parent atoms, whereas anions are larger due to the gain or loss of electrons affecting electron cloud distribution and repulsion forces.

A crystal lattice is a highly ordered structure consisting of a repeating pattern of atoms, ions, or molecules in three-dimensional space, which gives rise to the unique properties of crystalline solids. Understanding the geometry and symmetry of crystal lattices is crucial for determining the material's physical properties, such as conductivity, strength, and optical characteristics.

Coordination number is the total number of atoms, ions, or molecules that a central atom or ion holds as its nearest neighbors in a complex or crystal structure. It is a crucial factor in determining the geometry and properties of a compound, influencing its stability, reactivity, and physical characteristics.

Anions are negatively charged ions formed when atoms gain electrons, resulting in a surplus of electrons compared to protons. They play a crucial role in various chemical reactions and are essential in processes such as electrolysis and the formation of ionic compounds.
