The atomic radius of a chemical element is a measure of the distance out to which the …
The ionic radius is not a fixed property of a given ion, but varies with coordination number, spin state and other parameters. Nevertheless, ionic radius values are sufficiently transferable to allow periodic trends to be recognized. As with other types of atomic radius, ionic radii increase on descending a group. Meer weergeven 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 … 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 unit cell of a crystal. For example, … Meer weergeven • Atomic orbital • Atomic radii of the elements • Born equation • Covalent radius 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 … Meer weergeven The concept of ionic radii is based on the assumption of a spherical ion shape.
