The ionic radius drops from 103 pm for lanthanum ( III ) to 86.1 pm for lutetium ( III ).

The ionic radius drops from 102 pm for cerium ( III ) to 86.1 pm for lutetium ( III ).
13.
This change in spin state is a cooperative effect due to the higher ionic radius of Fe 2 + in the oxyhemoglobin moiety.
14.
The iron ( II ) ion has the same charge as magnesium ion and it has a very similar ionic radius to magnesium.
15.
Figure 2 shows a relationship between the ionic radius of trivalent rare-earth ions and the composition of some rare-earth borides.
16.
Additionally, the effective nuclear charge has increased, and thus the electrons are attracted more strongly towards the nucleus and the ionic radius decreases.
17.
The predicted ionic radius of the hexacoordinate Sg 6 + ion is 65 pm, while the predicted atomic radius of seaborgium is 128 pm.
18.
Sodium has a much larger ionic radius than potassium does, so during the quench event the sodium ions pop out of the crystal framework.
19.
In ionic compounds there arise characteristic distances between ion neighbours from which the spatial extension and the ionic radius of individual ions may be derived.
20.
In fact there is a very good linear correlation between hydration enthalpy and the ratio of charge squared to ionic radius, z 2 / r.
