Ionic radii of k
Web1 aug. 2002 · Potassium channels are able to select between K+ ions in favor of Na + ions, despite only a small difference in their ionic (i.e., Pauling) radii (0.133 nm vs. 0.095 nm, respectively). Theories of the physical origins of ion selectivity have a long and distinguished history ( Hille, 1992 ).

Web1 jan. 2024 · The radii of the ions as well as their diffusion coefficients obtained from the literature are shown in Table 2 [32], [33]. It can be seen that the ionic radius of Li+ is almost half of K +, while that of Cs + is approximately 30% higher. Table 2.
WebThe atomic radius of a chemical element is the distance from the center of the nucleus to the outermost shell of an electron. Since the boundary is not a well-defined physical entity, there are various non-equivalent definitions of atomic radius.
