8.23 Which metal in the first series of transition metals exhibits +1 oxidation state most frequently and why?

In the first transition series, Cu exhibits +1 oxidation state very frequently. It is because

Cu ( +1) has an electronic configuration of [Ar] 3d¹⁰

The completely filled d-orbital makes it highly stable. Hence, it shows a +1 oxidation state more frequently
