JEE Main2007Chemistryd and f Block ElementsActual
The actinoids exhibits more number of oxidation states in general than the lanthanoids. This is because
Options
- Athe 5 f orbitals are more buried than the 4 f orbitals
- Bthere is a similarity between 4 f and 5 f orbitals in their angular part of the wave function
- Cthe actinoids are more reactive than the lanthanoids
- Dthe 5 f orbitals extend further from the nucleus than the 4 f orbitals
Correct answer
D. the 5 f orbitals extend further from the nucleus than the 4 f orbitals
Step-by-step solution
The actinoids exhibit more number of oxidation states in general than the lanthanoids. This is because the 5 f orbitals extend further from the nucleus than the 4 f orbitals. Hence, (D) is correct.
