Choose the INCORRECT statement. A) Among the methods to separate the lanthanides are fractional precipitation and solvent extraction. B) Because the properties of the lanthanides are so similar, separation must be done in a series of repetitive steps. C) Lanthanides are reactive metals, that is they liberate H₂ from acids. D) The 4f electrons play a major role in chemical bonding. E) The pure lanthanide metals can be produced by electrolytic reduction from the +3 oxidation state.

Question
