Since all lanthanides and actinides belong to group IIIB or 3rd group they have common oxidation state of +3 as the most stable state. In addition to +3, they also show +2 and +4 states also. M+2 states they are good reducing agents. Actinides show higher oxidation states of +5, +6 and +7. For them +3 state is not the most stable state especially for the flfst four elements Based upon the information above answer the following questions Actinides which show higher uxidastion state +5, +6 and +7 states and respectively are
