WebFeb 6, 2024 · The ionic radius is half the distance between atomic ions in a crystal lattice. To find the value, ions are treated as if they were hard spheres. The size of an element's ionic radius follows a predictable trend on the periodic table. As you move down a column or group, the ionic radius increases. This is because each row adds a new electron shell. WebThe ionic radius is half the diameter of an ion when compared to the atomic radius, which is half the diameter of a neutral atom. Lastly, elements on the left side of the periodic table tend to make cations, compared to the right side of the periodic table, which tends to create anions. References.
