    The effective nuclear charge (Z_("eff")) takes into account the interelectronic repulsion in multielectron atoms. Slater's rule helps us in evaluating Z_("eff") for various species. Apply Slater's rules to answer the following questions. Z_("eff") for 3d electron of Zn=x Z_("eff") for 3d electron of Zn^(2+( = y Z_("eff") for 4s electron Zn = z Choose the correct option(s)
