Web16 sep. 2024 · The ionic radius (plural: ionic radii) is the measure of an atom's ion in a crystal lattice. It is half the distance between two ions that are barely touching each other. Since the boundary of the electron shell of an atom is somewhat fuzzy, the ions are often treated as though they were solid spheres fixed in a lattice. WebPeriodicity in atomic radius and ionic radius For normal elements (a) In a period from left to right effective nuclear charge increases because the next electron fills in the same shell. So the atomic size decreases.
