NEET Solved Paper 2017 Question 41
Question: The reason for greater range of oxidation states in actinoids is attributed to
Options:
A) 4f and 5d levels being close in energies
B) The radioactive nature of actinoids
C) Actinoid contraction
D) 5f, 6d and 7s levels having comparable energies
Show Answer
Answer:
Correct Answer: D
Solution:
- The correct option is D 5f, 6d and 7s levels having comparable energies Actinoids have a greater range of oxidation states due to comparable energies of 5f, 6d and 7s orbitals. Hence, all their electrons can take part in bond formation.
