Question

defination and difference of lanthanides and actinides

Answer 1

Lanthanoids are involved in the filling of 4f- orbitals whereas actinoids 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.

Differences between lanthanides and actinides  

Lanthanides have the ability to show a maximum oxidation state of +4 while actinides show oxidation states of +3, +4, +5, +6 and +7.

Lanthanides do not form complexes easily. Actinides have a greater tendency to form complexes with ligands such as thio-ethers.

All lanthanides are non-radioactive except promethium but actinides are radioactive in nature.

Lanthanides do not form oxocations, but actinides form oxocations such as UO+, PuO+, NpO2+.

Most of the lanthanides are colorless in nature but most of the actinides are colored ions.

Answer 2

Hola Friend

Here is your answer.....................

Defination:

The lanthanides and actinides are groups of elements in the periodic table. They are the elements that are often listed below the main section of the periodic table.

Difference of lanthanides and actinides are:

1.Lanthanides have the ability to show a maximum oxidation state of +4 while actinides show oxidation states of +3, +4, +5, +6 and +7.

2.Lanthanides do not form complexes easily. Actinides have a greater tendency to form complexes with ligands such as thio-ethers.

3.All lanthanides are non-radioactive except promethium but actinides are radioactive in nature.  

4.Lanthanides do not form oxocations, but actinides form oxocations such as UO+, PuO+, NpO2+.  

5.Most of the lanthanides are colorless in nature but most of the actinides are colored ions.

I hope it helps u
