NEET · Chemistry · STD 12 - 4. d and f- block elements
The reason for greater range of oxidation states in actinoids is attributed to
- A actinoid contraction
- B \(5f, \,6d\) and \(7s\) levels having comparable energies
- C \(4f\) and \(5d\) levels being close in energies
- D the radioactive nature of actinoids.
Answer & Solution
Correct Answer
(B) \(5f, \,6d\) and \(7s\) levels having comparable energies
Step-by-step Solution
Detailed explanation
Minimum energy gap between \(5 f, \,6 d\) and \(7s\) subshell. Thats why exitation will be easier.
