QNEET-2022-Ch-469: NEET 2022 Chemistry - Class 11 NEET-2022-Ch-469 Solution: Decrease in size from left to right in actinoid series is…
Decrease in size from left to right in actinoid series is greater and gradual than that in lanthanoid series due to 5f orbitals have greater shielding effect 4f orbitals are penultimate 4f orbitals have greater shielding effect 5f orbitals have poor shielding effect
Multiple Choice Options
- A 5f orbitals have greater shielding effect
- B 4f orbitals are penultimate
- C 4f orbitals have greater shielding effect
- D 5f orbitals have poor shielding effect
Step-by-Step Verified Solution
Due to more diffused nature of 5f orbitals as compared to 4f orbitals the shielding effect of 5f is poor, resulting in the decrease in size from left to right in actinoid series which is greater and gradual than that in lanthanoid series.
