Atomic and Ionic Radii (Section)
Consider the isoelectronic ions F- and Na+.
(a) Which ion is smaller?
(b) Using Equation 7.1 and assuming that core electrons contribute 1.00 and valence electrons contribute 0.00 to the screening constant, S, calculate Zeff for the 2p electrons in both ions.
(c) Repeat this calculation using Slater’s rules to estimate the screening constant, S.
(d) For isoelectronic ions, how are effective nuclear charge and ionic radius related?
