Solution: Detailed calculations show that the value of Zeff for the outermost electrons in Na and K atoms is 2.51+ and 3.49+ , respectively.What value do you estimate for Zeff experienced by the outermost elect

Detailed calculations show that the value of Z_eff for the outermost electrons in Na and K atoms is 2.51+ and 3.49+ , respectively.

What value do you estimate for Z_eff 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? What values do you estimate for Z_eff using Slater’s rules?

Does either method of approximation account for the gradual increase in Z_eff that occurs upon moving down a group?
