1.	Among the following pairs of orbitals which orbital will experience the larger effective nuclear charge? (a) 2s and 3s, (b) 4d and 4f, (iii) 3d and 3p
Answer» Solution :(i) 2s is closer to the NUCLEAR than 3s. Hence, 2s will experience LARGER effective nuclear charge. (ii) 4d (iii) 3p (for same reasons) ALTERNATIVELY, exact CALCULATIONS can be done by applying Slater's rules GIVEN on
