To determine the total number of valence electrons in a transition metal complex, we need to add up the valence electrons of the metal and the ligands. In this case, we have: - Pd: belongs to the d-block and has 10 valence electrons - PPh₃, ₄: each ligand has a phosphorus (P) atom, a sulfur (S) atom, and a phenyl (Ph) group. The valence electrons from each ligand are: - Ph group: 6 electrons (4 from C and 1 from each of the two attached H atoms) - S atom: 6 electrons - P atom: 5 electrons So the total valence electrons from each ligand are 17. Since we have three ligands, the total valence electrons from the ligands are 51. Thus, the total valence electrons for the complex is: 10 (from Pd) + 51 (from ligands) = 61 The closest choice to this is E (18), so E is the correct answer.
