Web4 sep. 2024 · September 4, 2024 by Alexander Johnson. 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. 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 ...

Ionic radius - Wikipedia

Ionic radius, rion, is the radius of a monatomic ion in an ionic crystal structure. Although neither atoms nor ions have sharp boundaries, they are treated as if they were hard spheres with radii such that the sum of ionic radii of the cation and anion gives the distance between the ions in a crystal lattice. Ionic radii are typically given in units of either picometers (pm) or angstroms (Å), with 1 Å = 100 pm. Typical values range from 31 pm (0.3 Å) to over 200 pm (2 Å).
