Cerium and Terbium behave as good oxidising agents in +4 oxidation state. Explain

Write the names and chemical formulae of any one are of iron and zinc each.

Name and write the chemical formulae Of the three oxide ores of iron.

Name the reducing agent used in the extraction of zinc from zinc oxide. Write the chemical equation for this reaction.

a) Name the ore of Iron? b) Which reduces lon from iron oxide in the blast furnace? c) Write the chemical equation for the reduction of iron.

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
