Answer:
The difference between the Lanthanides and actinides are explained below.
|
Lanthanides |
Actinides |
|
Lanthanides are involved in the filling of 4f- orbitals. The binding energy of 4f electrons is comparatively less than that of 5f-electrons. |
Actinides are involved in the filling of 5f-orbitals. The shielding effect of 5f-electrons is less effective as compared to that of 4f-electrons. |
|
Lanthanides are non-radioactive in nature except promethium |
Actinide series elements are radioactive. |
|
The compounds formed by lanthanides are less basic. |
compounds of actinides are highly basic. |
