Question

Which is characteristic oxidation state of Lanthanoids?

Answer 1

Answer:

The most stable oxidation state for lanthanide atoms is +3, but the +2 and +4 oxidation states are also common. Although the lanthanides are sometimes called the rare earths, the elements are not particularly rare. However, they are difficult to separate from one another.

Answer 2

Answer:

In the case of lanthanoids , +3 oxidation state is most common.

That is, Ln(III) compounds are predominant.

However, +2 and +4 oxidation states can also be found in the solution or in solid compounds.
