Textbook Question

Chapter 7, Problem 15E

Detailed calculations show that the value of Z_e_f_f for the outermost electrons in Na and K atoms is 2.51 + and 3.49 +, respectively. (a) What value do you estimate for Z_e_f_f 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? (b) What values do you estimate for Z_e_f_f using Slater's rules? (c) Which approach gives a more accurate estimate of Z_e_f_f? (d) Does either method of approximation account for the gradual increase in Z_iff that occurs upon moving down a group? (e) Predict Z_e_f_f for the outermost electrons in the Rb atom based on the calculations for Na and K.
