Some soft-sphere ionic radii are in the table. These radii are larger than the crystal radii given above (Li +, 90 pm; Cl −, 167 pm). Inter-ionic separations calculated with these radii give remarkably good agreement with experimental values. Some data are given in the table. 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, the length of each edge of the unit cell of sodium chloride is found to be 564.02 pm. … 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.

Web23 jun. 2024 · Each proton carries a +1 charge; the more protons an atom or ion contains the stronger the attraction it poses on its electron cloud. A nucleus of strong positive charge pulls its electron cloud towards itself tightly such that the latter would have a small radius. The periodic table is arranged in the order of increasing proton number.
