Silver (Ag) has completely filled d-orbitals (4d10) in its ground state. How can you say that it is a transition element?
In its ground state, silver possesses a totally filled 4d4d-orbital (4d10,5s1)(4d10,5s1) .The oxidation states of silver are now +1+1 and +2+2. An electron is removed from the s-orbital in the +1+1 oxidation state. The d-orbital, on the other hand, loses one electron in the +2+2 oxidation state. As a result, the d-orbital is now incomplete (4d9)(4d9). As a result, it's a transitional element.
