Question
Give any two difference between lanthanoids and actinoids.
Open in App
Solution
Lanthanides are involved in the filling of 4f-
orbitals whereas actinides 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.
