Which metal in the first transition series (3d series) exhibits + 1 oxidation state most frequently and why?
Advertisements
उत्तर
Cu is the only metal in the first transition series (3d series) which shows +1 oxidation state most frequently. This is because the electronic configuration of Cu is 3d10 4s1 and after losing one electron it acquires a stable 3d10 configuration.
