The electron configurations for Copper and Silver can also be slightly different due to electron promotion. Electron promotion explains how the valences (ions) of these atoms form. Another possibility:
Cu = [Ar]4s13d10 (4s1 is the valence shell, and when the electron is lost, it creates the +1 charge of Cu).
Ag = [Kr]5s14d10 (5s1 is the valence shell, and when the electron is lost, it creates the +1 charge of Ag).
