WebFor example, Both O 2-, Mg 2+ have 10 electrons but they don’t have the same ionic radius as the effective nuclear charge in both of them is different. The radius of a cation will be smaller than that of the anion as a cation will have a greater positive charge (i.e. number of protons) so it will attract the electrons in the outermost orbital with greater force and … WebThe ionic radii of trivalent REE ions are about 1 Å, which are compatible to those of Ca 2 +, Na +, Th 4 +, etc., and are significantly larger than those of other trivalent ions such as B 3 +, Al 3 +, and Fe 3 + (Miyawaki and Nakai, 1996). Ionic radii of the trivalent REE ions are systematically reduced from La to Lu with increasing atomic number. irc ss560f 90/90-14
