Verified step by step guidance

Step 1: Begin by identifying the atomic numbers of palladium (Pd) and silver (Ag). Palladium has an atomic number of 46, and silver has an atomic number of 47.

Step 2: Write the electron configuration for palladium (Pd). The electron configuration is determined by filling the orbitals in order of increasing energy. For Pd, the electron configuration is [Kr] 4d^10 5s^0.

Step 3: Write the electron configuration for silver (Ag). Similarly, fill the orbitals for Ag, which has one more electron than Pd. The electron configuration for Ag is [Kr] 4d^10 5s^1.

Step 4: Compare the electron configurations of Pd and Ag. Notice that Ag has one more electron than Pd, which is added to the 5s orbital, resulting in Ag having 1 more s electron than Pd.

Step 5: Analyze the d electrons. Both Pd and Ag have the same number of d electrons, which is 10. Therefore, Ag does not have more d electrons than Pd.
