Use Slater's rules (given in slide 31 of lecture) to calculate Zeff (use formulae given in slide 32) for the valence electron of Ru, Rh and Pd. Comment on the trend you observe across the period. (For Pd just consider any one valence electron) Find the electron configurations and write them according to Slater's prescription (lecture slide 33). Then use the rules to find the screening constant (s) using s = 1.00N2 + 0.85N1 + 0.35N0 where No = number of other electrons in the same shell N1 = number of electrons in the (n-1) shell N2 = number of electrons in other (n-2) and smaller shells and then Zeff using formulae Zeff = Z –s where Z is total nuclear charge.
