Though copper, silver and gold have completely filled set of d-orbitals yet they are considered as transition metals. Why?

Cu, Ag and Au have completely filled d-orbitals yet they are regarded as transition elements explain.

Silver atom has complete filled d-orbitals (4d^(10)) in its ground state. Yet, it is considered as transition element. Why?

Both Cu and Zn have completely filled 3d atomic orbital. Cu is considered as transition element but Zn is not. Explain.

Silver atom has completely filled d-orbital (4d^10) in its ground state. How can you say that it is a transition elements?

Why is copper considered a transition metal, although it has completely filled d-orbital (3d^10) ?

Which of the 3d series of the transition metals exhibits the largest number of oxidation states and why?

Samples of four metals A,B,C and D were taken and added to the following solutions one by one.The results obtained have been tabulated as follows. Use the table above to answer the following questions about metals A,B,C and D. (i)Which is the most reactive metal? (ii)What would you observe if B is added to a solution of copper (II) sulpahate? (iii)Arrange the metals A,B,C and D in the order of decreasing reactivity.
