Which metal in the 3d series exhibits +1 oxidation state most frequently and why? - Chemistry

Which metal in the 3d series exhibits +1 oxidation state most frequently and why?

Short/Brief Note

1. The first transition metal copper exhibits only +1 oxidation state.

2. It is unique in 3d series having a stable +1 oxidation state.

Cu (Z = 29)

Electronic configuration is [Ar] 3d¹⁰ 4s²

3. So copper element only can have +1 oxidation state.
