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(g)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

Quizplus · Accepted Answer

The 4f electrons in lanthanides are generally not involved in chemical bonding. They are shielded by the 5s and 5p electrons, making the 4f electrons play a minor role in the chemical properties of the lanthanides.
