The actinoids Exhibit more member of oxidation states in general than the lanthanoids. This is because
- a)the 5f-orbitals are more buried than the 4f-orbita!s
- b)there is a similarity between 4f and 5f-orbitals in their angular part of the wave function
- c)the actinides are more reactive than the lanthanides
- d)the 5f-orbitals extend farther from the nucleus than the 4f-orbitals
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
The actinoids Exhibit more member of oxidation states in general than ...
The wide range of oxidation state of actinoids is due to the fact that the 5f, 6d and 7s energy levels are of comparable energies and all these three subshells can participate in comparison to lanthanoid. The 5f orbitals extend farther from the nucleus than the 4f orbitals.

Understanding Oxidation States in Actinoids vs. Lanthanoids
The differences in oxidation states between actinoids and lanthanoids can be attributed to the characteristics of their respective f-orbitals.
1. Orbital Extent
- The 5f-orbitals in actinoids extend farther from the nucleus compared to the 4f-orbitals in lanthanoids.
- This greater radial extension allows for more effective interaction with surrounding atoms and ligands, facilitating the loss of electrons.
2. Accessibility of Electrons
- The increased distance of the 5f-orbitals means that the electrons in these orbitals are less tightly bound to the nucleus.
- This makes it easier for actinoid elements to exhibit a wider range of oxidation states, as they can lose electrons more readily.
3. Reactivity of Actinides
- Actinides are generally more reactive than lanthanides due to their ability to adopt multiple oxidation states.
- This reactivity can be attributed to their larger atomic size and the unique properties of the 5f electrons.
4. Summary of Oxidation States
- Actinoids can show oxidation states ranging from +3 to +7, while lanthanoids typically exhibit +3 as their primary oxidation state.
- The ability to access higher oxidation states in actinoids is crucial for their chemistry and applications in various fields, including nuclear technology.
In conclusion, the extended nature of the 5f-orbitals in actinoids is the key factor enabling greater variability in oxidation states compared to the 4f-orbitals of lanthanoids.
