In context of the lanthanoids, which of the following statements is not correct?

All the members exhibit +3 oxidation state

Because of similar properties the separation of lanthanoids is not easy.

Availability of 4f electrons results in the formation of compounds in +4 state for all the members of the series.

There is a gradual decrease in the radii of the members with increasing atomic number in the series.
