Abstract On the basis of the vanguard electron model a formula for direct calculation of the maximum ionic probability radius, R_f, has been deduced: where α_0=Boron radius; R=Rydberg constant; Z=effective nuclear charge and t=spectroscopic state corresponding to the configuration of ion.An empirical formula for the contact radius of iso-electronic ion, R_0, may be expressed by: where k and b are empirical values.These formulas are characterized by clear physical definition, simple calculation and high accuracy of the data obtained.
