The ionic radii of Rf⁴⁺, Db⁵⁺ and Sg⁶⁺

Commonly used calculations of ionic radii (IR) based on the correlation between IR and the maximum radial charge density (R_max,np) give overestimated values for the heaviest elements. That is because the method does not take into account the significant splitting of outermost p orbitals into p_1/2 and p_3/2. Using 2j+1 weighted expectation orbital radii, (r_np), instead of R_max,np, new values of IR for Rf⁴⁺, Db⁵⁺ and Sg⁶⁺ have been calculated. These IR values for coordination number 6 are equal to 74 (instead of 79) pm for Rf⁴⁺, 66 (instead of 74) pm for Db⁵⁺ and 63 (instead of 65) pm for Sg⁶⁺.
