• the correct electronic configuration of Ag (not Ag+)

  is [Kr]4d10 5s1

  this is according to Aubaus principle…….

  and now for Ag+……

  1 electron is remove from the 5s orbital……….

  so finally electronic configuration becomes…….

  c. [Kr]4d10

  all the best……..

• Ag+ has 46 electrons in 4 shells, having lost the one valence electron from its 5th shell.

  Shell 1 = 2, Shell 2 = 8, Shell 3 = 18, and Shell 4 = 18.

  Shell 5 will normally have 1 electron when as a stable element.
