The reason for greater range of oxidation states in actinoids is attributed to :

Monjur Alahi

The reason for greater range of oxidation states in actinoids is attributed to :
(1) actinoid contraction
(2) 5f, 6d and 7s levels having comparable energies
(3) 4f and 5d levels being close in energies

(4) the redioactive nature of actinoids

(2) 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.

Assign a possible reason for the following : (a) Stability of + 5 oxidation state decreased and that of + 3 oxidation

[Hint :   (a) Due to inert pair effect. (b) Due to more bond dissociation enthalpy of O – H as compared to S – H bond. (c) Due to more steric hindrance...

Compare the chemistry of actinoids with that of the lanthanoids with special reference to: (i) electronic configuration

(i) Electronic configuration The general electronic configuration for lanthanoids is [Xe]54 4f0-14 5d0-1 6s2 and that for actinoids is [Rn]86 5f1-14 6d0-1 7s2. Unlike 4f orbitals, 5f orbitals are not deeply...

The actinoids exhibit more number of oxidation states in general than the lanthanoids.

(a) : As the distance between the nucleus and 5f orbitals (actinides) is more than the distance between the nucleus and 4f orbitals (lanthanides) hence the hold of nucleus on...

Larger number of oxidation states are exhibited by the actinoids than those by the lanthanoids,

(c) : Actinoids show different oxidation states such as +2, +3, +4, +5, +6 and +7. However +3 oxidation state is most common among all the actinoids. The wide range...

A rapid increase in the rate of inflation is sometimes attributed to the “base effect”. What is “base effect”?

(c) Base effect is almost an ubiquitous term which says that the previous data affects the calculation of the current data.

Assertion (A): Oxidation involves loss of electrons. Reason(R) :During oxidation number of an element decreases.

(b)Both A and R are true and R is not the correct explanation of the A.
