Gourary and Adrian1 have derived a set of new ionic radii for the alkali metal and halide ions using the experimental radii of sodium (1.17 Å) and chloride (1.64 Å) ions2 as standard. These ...

Larger K+ (ionic radius: 1.3 Å) can selectively permeate larger Na + (ionic radius: 1.0 Å) through biological potassium ion channels, with selectivity ratios greater than 1000-fold. Scientists have ...

Its atomic radius is 0.160nm and the (+4) ionic radius is 0.080 nm. In the solid state Zirconium has a hexagonal-close-packed crystal structure . Zirconium has a Young's modulus of 99 GPa, a yield ...
