Hi Bob, Well lets see, webelements provide three or four different atom sizes, some derived theoretically and others empirically, and five measurements of the monovalent ion. The size depends upon the geometry and the environment.
The Tanner calculation is for the *effective* ion size in an aqueous environment. The wave method (in water? sonic or light?) has wide use in scientific instruments, but from what I have seen so far is reaching its limits at these sizes. But the difference is not large and may lie in the margin of error.
