QNEET-2017-Ch-960: NEET 2017 Chemistry - Class 12 NEET-2017-Ch-960 Solution: The reason for greater range of oxidation states in actinoids…
The reason for greater range of oxidation states in actinoids is attributed to actinoid contraction 5f 6d and 7s levels having comparable energies 4f and 5d levels being close in energies the radioactive nature of actinoids.
Multiple Choice Options
- A actinoid contraction
- B 5 f , 6d and 7s levels having comparable energies
- C 4 f and 5d levels being close in energies
- D the radioactive nature of actinoids.
Step-by-Step Verified Solution
Minimum or comparable energy gap
between 5f, 6d and 7s subshell makes electron
excitation easier, hence there is a greater range
of oxidation states in actinoids.
