Atomic and ionic radii represent fundamental descriptors for the spatial extent of atoms and ions within materials and molecules. Despite their seeming simplicity, precise characterisation of these ...
Ever stop to contemplate the size of an atom or ion? Martin Rahm, Roald Hoffmann, and Neil W. Ashcroft have. For consistency’s sake, these Cornell University scientists have just completed a ...
The Golden ratio which appears in the geometry of a variety of creations in Nature is found to arise right in the Bohr radius of the hydrogen atom due to the opposite charges of the electron and ...
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 ...
