Ionic Radius: Definition, Examples, Chart, & Periodic Trend

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 • Covalent radius • Electride Meer weergeven The concept of ionic radii is based on the assumption of a spherical ion shape. However, from a group-theoretical point of view the assumption is only justified for ions that … Meer weergeven • Aqueous Simple Electrolytes Solutions, H. L. Friedman, Felix Franks Meer weergeven WebIonic radius is the distance from the nucleus of an ion up to which it has an influence on its electron cloud.
