Abstract

Graphs of the total radius (the distance between an anionic nuclei and a cationic nuclei in a crystal) of sodium halides and alkali metal fluorides versus total limiting equivalent conductivities were plotted. For the hard ions Na+ and F−, whose behaviour approaches a hard spherical model, it was determined that radii values could be obtained using differences in limiting equivalent conductivities and ionic crystal data. From the determined radii of sodium and fluoride ions and known crystal data, radii of other alkali metal halides were calculated.

Notes

  1. When the dipoles of the water molecules are oriented exactly towards the positive charge of the cation, the potential energies of the water molecules in the first coordination sphere are much greater than the potential energies of free water molecules. Thus, when the dipole of the water molecule is oriented towards the centre of the positive charged ions, (r ion + r water)2 is inversely proportional to potential energy because the other parameters such as the dipole moment of water and the charge of the ion remain constant.
