Class 12 Chemistry D and F Block Elements Oxidation state in Actinoids

Oxidation state in Actinoids

  • In general the oxidation state of these elements is +3 (similar to lanthanides).
  • They also exhibit +4 oxidation states.
  • Some of the elements also exhibit higher oxidation states.
  • The oxidation state initially rises to the middle of the series (+4 for Th to +5, +6 and +7 for Pa, V and Np) and then descends in the succeeding elements.
