Lanthanoids 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.
