Question

Compare between lanthanoids and actinoids.​

Answer 1

Answer:

Lanthanide

Lanthanoids have a bright and silvery appearance.

Actinoids.

Most of the actinides ions are deeply coloured

Answer 2

Explanation:

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.
