"Web7 jun. 2024 · Ionic radii depend on oxidation state (higher charge => smaller cation size, larger anion size) We can build up a table of ionic radii by assuming that the bond length is the sum of the radii (r + + r -) if the ions are in contact in the crystal. Consider for example the compounds MgX and MnX, where X = O, S, Se. " - Ionic radii of ba2+

Ionic radii of ba2+

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).
