Question

Write one similarity and two differences between lanthanoids and actinoids

Answer 1

Write one similarity and one difference between the chemistry of lanthanoids and that of actinoids. (i) Both have mainly an oxidation state of + 3. (i) Lanthanoids have less tendency towards complex formation whereas actinoids have greater tendency towards complex formation.

Answer 2

Explanation:

Difference- actinoids are radioactive and lanthanoids are not/ actinoids show wide range of oxidation states but lanthanoids don't (or any other correct difference). Detailed Answer: Similarity: Both lanthanoid and actinoid elements are stable in +3 otdation state.
