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

Text Solution

Verified by Experts

Copper exhibits + 1 oxidation state most frequently. Electronic configuration of Cu in the ground state is `3d^(10)4s^(1)`. So copper atom can easily lose `4s^(1)` electron to give the stable `3d^(10)` configuration. So it shows + 1 oxidation state.
