Shannon 31 Aug 1976 - Acta Crystallographica Section A Abstract: The effective ionic radii of Shannon & Prewitt [Acta Cryst. (1969), B25, 925-945] are revised to include more unusual oxidation states and coordinations.
Webb11 maj 2024 · The ionic radii are calculated from the internuclear distances in ionic crystals by assuming the radius of one ion. Though the ionic radii do not remain constant in different crystals, the variations are small, and the radii (in pm) are found to be as: r (Na) = r (Li) + 25 ± 3 r (Cl) = r (F) + 50 ± 4 r (K) = r (Na) + 32 ± 2 r (Br) = r (Cl) + 16 ± 2 how to ev train dragonitelee and perrins steak sauce boldWebbShannon R D.
