Question

write two similarities and two difference between lanthanides and actinoids​

Answer 1

Answer.

similarities

Both have a prominent oxidation state of +3. They are involved in the filling of (n-2) f orbitals. They are highly electropositive and very reactive in nature.

difference

lLanthanoids are involved in the filling of 4f- orbitals whereas actinoids are involved in the filling of 5f-orbitals. The binding energy of 4f electrons is comparatively less than that of 5f-electrons. ... Lanthanides are non- radioactive in nature except promethium whereas all actinide series elements are radioactive.
