Question

Actinoids exhibit a much larger number of oxidation than the lanthanides

Answer 1

Answer:

Actinides exhibits larger oxidation states than lanthanides, because of very small energy gap between 5f, 6d and 7s sub shells. Thus, the outermost electrons get easily excited to the higher energy levels, giving variable oxidation states.
