Strong dissociation in water is encouraged by a combination of high difference and large ionic radius.

The spin state of the complex also affects an atom's ionic radius.

For ions in solution Shannon's "effective ionic radius" is the measure most often used.

Due to its large ionic radius, caesium is one of the "incompatible elements".

The ligand radius should not be confused with the ionic radius.

Nevertheless, ionic radius values are sufficiently transferable to allow periodic trends to be recognized.

The ionic radius is expected to decrease regularly for Mn to Zn.

The paper by Aue et al. gives a good discussion of the methods by which the ionic radius was determined.

The ionic radius of fluoride is much larger than its covalent radius.

Lithium has a diagonal relationship with magnesium, an element of similar atomic and ionic radius.

The ionic radius is not a fixed property of a given ion, but varies with coordination number, spin state and other parameters.

Compatibility of an ion is controlled by two things: its valence and its ionic radius.

An "anomalous" ionic radius in a crystal is often a sign of significant covalent character in the bonding.

By chance it is the ionic radius of zinc that is almost equal to that of magnesium.

In general, ionic radius decreases with increasing positive charge and increases with increasing negative charge.

An ionic radius of 0.0192 nm and a coordination number of 6 for Md was predicted using empirical correlations.

In fact there is a very good linear correlation between hydration enthalpy and the ratio of charge squared to ionic radius, z/r.

Note that scandium has many unique boron compounds, as shown in figure 2, because of the much smaller ionic radius compared with other rare-earth elements.

The strength of the complexes formed increases as the ionic radius decreases, so solubility in the organic phase increases.

Additionally, the effective nuclear charge has increased, and thus the electrons are attracted more strongly towards the nucleus and the ionic radius decreases.

The Stern layer accounted for ions' finite size and consequently ions have a closest approach to the electrode on the order of the ionic radius.

The effect of the lanthanide contraction is clear, in that the 6-coordinate telluride ion (Te) has an ionic radius of 221 pm.

Sodium has a much larger ionic radius than potassium does, so during the quench event the sodium ions pop out of the crystal framework.

The change in spin state is a cooperative effect of higher crystal field splitting and smaller ionic radius of Fe in the oxy- moiety.

Density, melting and boiling points, and atomic and ionic radii tend to increase towards the chalcogens with higher atomic numbers.
