Chemistry · Lanthanoids: Electronic configuration, oxidation states and Lanthanoid contraction
The Lanthanide contraction relates to:
The Lanthanide contraction relates to:
- A. oxidation states
- B. magnetic state
- C. atomic radius
- D. valence electrons
Step-by-step solution
The lanthanide contraction refers to the decrease in atomic and ionic radii across the lanthanide series (La to Lu) caused by poor shielding of 4f electrons, leading to increased effective nuclear charge. This phenomenon directly relates to atomic radius, not oxidation states, magnetic states, or valence electrons.
