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 … Meer weergeven Ions may be larger or smaller than the neutral atom, depending on the ion's electric charge. When an atom loses an electron to form a cation, the other electrons are more attracted to the nucleus, … Meer weergeven The distance between two ions in an ionic crystal can be determined by X-ray crystallography, which gives the lengths of the sides of the Meer weergeven • Atomic orbital • Atomic radii of the elements • Born equation Meer weergeven The concept of ionic radii is based on the assumption of a spherical ion shape.

Friedman, Felix Franks Meer weergeven WebWhen the ionic radius Rion of H 3 O + (141 pm) is assumed to be rs, the c value is 4.8 for H 2 O. Following the classical relation, c value is either 4 nor 6, then the rs values are 168 or 112 pm for 4 or 6, respectively. The estimate of c = 4.8 of H 2 O is tentative, but we will use this value in our discussion.
