Which of the following statements regarding Lanthanides is false?
- A All lanthanides are solid at room temperature
- B Their usual oxidation state is +3
- C They can be separated from one another by ion-exchange method
- D Ionic radii of trivalent lanthanides steadily increases with increase in atomic number
Answer & Solution
Correct Answer
(D) Ionic radii of trivalent lanthanides steadily increases with increase in atomic number
Step-by-step Solution
Detailed explanation
The option (d) is false as lonic radi of trivalent lanthanides decreases with increase in atomic number due to lanthanoid contraction.
