Lanthanides and Actinides resemble in:
Correct answer: C. Electronic configuration
- A. Ionisation state
- B. Oxidation state
- C. Electronic configuration
- D. Formation of complexes
Explanation
Both lanthanides and actinides have similar electronic configurations. They both have their valence electrons in f-orbitals, which are shielded from the outer environment by the filled 5s and 6s orbitals. This gives them unique electronic and chemical properties, including their high electron density, magnetic and spectroscopic properties.

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
