5. Select the appropriate statement. a) Both actinoids and lanthanoids are less basic b) Both actinoids and lanthanoids are electropositive c) Both actinoids and lanthanoids do not exhibit magnetic and spectral properties d) Both actinoids and lanthanoids do not show same oxidation of +3
Answer: b Explanation: In many ways, lanthanides and actinides are similar since they both entail the filling of f-orbitals. For both lanthanides and actinides, the most frequent oxidation state is +3. Both are electropositive and, as a result, very reactive. Both lanthanides and actinides have magnetic and spectroscopic characteristics.
