1.	Choose the correct statement.(a) Both actinoids and lanthanoids are less basic(b) Both actinoids and lanthanoids do not show same oxidation of +3(c) Both actinoids and lanthanoids do not exhibit magnetic and spectral properties(d) Both actinoids and lanthanoids are electropositiveI got this question during an online interview.This intriguing question originated from D and F-Block Elements topic in chapter D and F-Block Elements of Chemistry – Class 12
Answer» Correct option is (d) Both actinoids and lanthanoids are electropositive Explanation: LANTHANIDES and ACTINIDES involve filling of f-orbitals and thus are similar in MANY respects. The most common OXIDATION state is +3 for both lanthanides and actinides. Both are electropositive in nature and thus very reactive. Magnetic and spectral properties are exhibited by both lanthanides and actinides.
