(a) If the core electrons were totally effective at screening the valence electrons and the valence electrons provided no screening for each other, what would be the effective nuclear charge acting on the 3s and 3p valence electrons in P?
(b) Repeat these calculations using Slater's rules.
(c) Detailed calculations indicate that the effective nuclear charge is 5.6+ for the 3s electrons and 4.9+ for the 3p electrons.Why are the values for the 3s and 3p electrons different?
(d) If you remove a single electron from a P atom, which orbital will it come from? Explain.
