Answer 1

${ \sf{ \underline{Hey \: There! }}} \\ \\ \star \: { \mathtt{Similarities}} \: \implies \:$

→ Both involve filling of f orbital .

→ Both show contraction [ Lanthanoid & Actenoid contraction ]

→ Both show variable oxidation state.

→ Both are strong reducing agents.

→ Both have a tendency of complex formation .

$\star \: { \mathtt{Differences}} \: \implies$

→ Lanthanoids involve filling of 4f orbital and Actenoids involve filling of 5f orbital .

→ Lanthanoid contraction is greater than Actenoid contraction.

→ Lantanoid show only +2, +3 and +4 oxidation state. Actenoids show oxidation states upto +7.

→ Actenoids have less tendency of complex formation than Lanthanoids.
