According to Slater's rule , correct order of Z_("eff") on valence shell electron is :

Calculate the screening constant in Zn . a. For a 4 s -electron b. For a 3 d -electron

Effective nuclear charge (Z_(eff)) is the net attractive force on electrons under consideration and is equal to: Z_(eff) = Z - sigma (nuclear charge - screening constant). Z_(eff) or sigma is calculated by Slater's formula, as given. If one electrons is present in the outermst orbit, there will be no screening in that orbital. Each electrons contribute, 0.35 (total electrons minus one electron) present in the outermost shell. A contribution of 0.85 for each electrons is taken in the (n - 1)th shell. Which of the following statement is wrong?
