Silver atom has completely filled d orbitals (4d10) in its ground state. How can you say that it is a transition element?

Silver has a completely filled 4d orbital in its ground state and Ag shows two oxidation states of +1 and +2. In the +1 state, an electron is removed from the s-orbital but in +2 state electron is removed from d-orbital. Thus now d-orbital becomes incomplete.
Final Answer
Hence, we can say that although silver atom has completely filled d orbitals (4d10) in its ground state still it is a transition element.
