Using the hard-sphere model with the existing tabulated values of ionic radii to calculate the lattice parameters of minerals does not always match experimental data ...

How does ionic radius and charge affect ionic bonding? What is polarisation and polarising power? How do electron density maps provide evidence for ions? All this and more covered in this ...

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 ...

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 ...

This PowerPoint lesson explains the trends in atomic and ionic radius, helping IBDP Chemistry students understand periodicity through effective nuclear charge and electron shielding. Designed for ...
