Shannon ionic radii table
http://abulafia.mt.ic.ac.uk/shannon/ WebbAppendix 2 of the Shackelford textbook lists the atomic and ionic radii of many elements in the periodic table. (Note that a full description of the ionic radii considers that they change not only based on the valence state, but also the coordination number. These radii are known as Shannon radii in honor of R.D. Shannon).
