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

Text Solution

Verified by Experts

Copper in the first transition series exhibits `+1` oxidation statemost frequencly . This is because Cu is `3d^(10) 4s^(1)` . When one electron is lost, the configuration becomes most stable due to fully filled `d^(10)` configuration.
