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

Options

  1. AThere is a gradual decrease in the radii of the members with increasing atomic number in the series.
  2. BAll the members exhibit +3 oxidation state.
  3. CBecause of similar properties the separation of lanthanoids is not easy.
  4. DAvailability of 4f electrons results in the formation of compounds in +4 state for all the members of the seri

Correct answer

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

Step-by-step solution

Availability of 4 f electrons does not result in the formation of compounds in +4 state for all the members of the series.
