An – actinide **Depending on the isotopes Some actinides can exist in several oxide forms such as An2O3, AnO2, An2O5 and AnO3. For all actinides, oxides AnO3 are amphoteric and An2O3, AnO2 and An2O5 are basic, they easily react with water, forming bases: An2O3 + 3 H2O → 2 An(OH)3. WebLanthanides and actinides have a high Oxidation State of +3. These elements are filled with (n-2) f orbitals. Lanthanides and actinides are both reactive and electropositive.

WebActinides show variable oxidation states because of the smaller energy gap between 5f, 6 d and 7s orbitals. Though 3+ is the most stable oxidation state, other oxidation states are possible because of the good shielding of f-electrons. ... The maximum oxidation state first increases up to the middle of the series and then decreases i.e. it ... WebThe oxidation state of each of the 15 actinides in the group is different. Generally, the oxidation state of actinides ranges between +2 to +7 O.S. Here are the values of the oxidation state of some of the actinides. Oxidation state of Actinium: +3 O.S.
