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 result that the size of the atom increases. The ionic radius is not a fixed property of a given ion, but varies with coordination number, spin state and other parameters. ... Shannon states that "it is felt that crystal radii correspond more closely to the physical size of ions in a solid."[6] The two sets of data are listed in the two ...
