Shannon atomic radii
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. Each edge of the unit cell of sodium chloride may be considered to have the atoms arranged as Na ∙∙∙Cl ∙∙∙Na , so the edge is twice t… WebbFor more details, please refer to the following paper: AAB Baloch et. al. “Extending Shannon's ionic radii database using machine learning,” Physical Review Materials, Vol. …

WebbThe interatomic distances chosen were the sum of ionic radii (crystal radii) of the cation and an- ion determined by Shannon and Prewitt. Each atom location is an octahedral site … Webb16 dec. 2015 · As a result, the gathering of Na + shields the backside of the Pt cathode to some extent, hindering H + from being reduced to H atoms by generating a large Coulomb repulsive force. Therefore, many H + are forced to squeeze into the interface between PMMA and Pt and accept electrons therein.
