List of ionic radii
The list of ionic radions is an alphabetically sorted list of all chemical elements and their ionic radii , depending on their charge or oxidation number .
The values are based on the ionic radius of 140 pm determined by Linus Pauling for an O 2− ion and thus for the coordination number 6. Exceptions are marked with a corresponding Roman numeral. The abbreviations ls and hs stand for low-spin and high-spin (see also Spin Crossover ).
