Which of the following statement is not correct?
La(OH)3 is less basic than Lu(OH)3
In lanthanide series ionic radius of Ln3+ * ions decreases
La is actually an element of transition series rather than lanthanide series
Atomic radii of Zr and Hf are same because of lanthanide contraction
La(OH )3 is more basic than Lu(OH)3. This is because ionic
size of La3+ on is more than La3+ ion (Fajan's rule).
