Lanthanoids are involved in the filling of 4f orbitals where as actniods are involved in the filling of 5f orbitals. The binding energy of 4f electrons is comparatively less than that of 5f electron. Lanthanids are non radioactive in nature except promenthium whereas all actinide series elements are radioactive.
