Ionstralen van elementen als functie van hun lading en spintoestand. De getallen zijn op basis van metingen aan kristallen. De waarden zijn in pm. (ls = low spin, hs = high spin). Ionen zijn zes gecoördineerd, tenzij tussen haakjes een ander getal staat:
Bijvoorbeeld. 146 (4) betekent het vier gecoördineerde stikstofatoom met 4 liganden als ${\ce {N^{3-}}}$ (bijvoorbeeld ${\ce {NH4^{+}}}$) heeft een straal van 146 pm.
