Question

Part A) What value do you estimate for Zeff experienced by the outermost electron in both Na and K by assuming core electrons contribute 1.00 and valence electrons contribute 0.00 to the screening constant?

Part B) What values do you estimate for Zeff using Slater's rules?

Part C) Which approach gives a more accurate estimate of Zeff ?
1. The first method.
2. The second (Slater) method.


Part D) Does either method of approximation account for the gradual increase in Zeff that occurs upon moving down a group?
1. Yes, both methods account for the gradual increase in Zeff.
2. Yes, the first method accounts for the gradual increase in .
3. Yes, the second method accounts for the gradual increase in .
4. No, neither of the methods above accounts for the gradual increase in
