JEE Main 2007Annual, Paper 1ChemistryEasyd- and f-Block Elements158× since 2002The actinoids exhibits more number of oxidation states in general than the lanthanoids. This is because :AOption A. the 5f orbitals are more buried than the 4f orbitalsBOption B. there is a similarity between 4f and 5f orbitals in their angular part of the wave functionCOption C. the actinoids are more reactive than the lanthanoidsDOption D. the 5f orbitals extend further from the nucleus than the 4f orbitalsCheckSkip · show solution
