Web8.3 : Ionic Radii. Ionic radius is the measure used to describe the size of an ion. A cation always has fewer electrons and the same number of protons as the parent atom; it is smaller than the atom from which it is derived. For example, the covalent radius of an aluminum atom (1 s2 2 s2 2 p6 3 s2 3 p1) is 118 pm, whereas the ionic radius of an ... http://abulafia.mt.ic.ac.uk/shannon/

WebAtomic radii (Å) Li 1 Mg 1. Ionic radii (Å)Li+ 0 Mg2+ 0. (i) Atomic volumes of Li and Mg are quite similar. Li 12 mL/mole Mg 13 mL/mole 3. Both have high polarising power (ionic potential) Polarising power (Φ) = 2 (Ionic radius) Ioniccharge Cations with large ionic potentials have a tendency to polarise the anions and to give partial covalent WebSo the ions of an atom are treated as if they were spheres. The ionic radius can easily be a little smaller or larger than the atomic radius, which is the radius a neutral atom of the element possesses. Finding Ionic Radius. Since ions tend to exist in bonds, the ionic radius can be found via the ionic bond between two atoms.
