Silver has completely filled d- orbital but it is regarded as a transition element why???

Expert Answer:

In the ground state, Ag has a completely filled 4d orbital (4d10 5s1).

Silver shows two oxidation states (+1 and +2).

An electron is removed from the s-orbital in the +1 oxidation state.

However, in the +2 oxidation state, an electron is removed from the d-orbital and so the d-orbital becomes incomplete (4d9).

Hence, it is a transition element.
