Solution

Q.
The reason for greater range of oxidation states in actinoids is attributed to [2017]

1 actinoid contraction

2 $5 f, 6 d$ and $7 s$ levels having comparable energies

3 $4 f$ and $5 d$ levels being close in energies

4 the radioactive nature of actinoids.

Ans.
(2)

Actinoids have a greater range of oxidation states due to comparable energies of $5 f, 6 d$ and $7 s$ orbitals. Hence, all their electrons can take part in bond formation.

Solution

Q. The reason for greater range of oxidation states in actinoids is attributed to [2017]
