Give any two difference between lanthanoids and actinoids.


The difference between the Lanthanides and actinides are explained below.



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.
