Wht is the difference between Lanthanides and Actinides?
are radioactive and the actinides are not
describe the complex formation by lanthanides?
Scientists are uncertain about the electronic structure of the Actinides because they have short lifespans. Some of the actinides have such short half lives that it is impossible to figure out their exact chemistry.
The nuclear structure is more important because the nuclei of actinides are unstable and spontaneously break apart
what is the difference between 201 and 201K
are radioactive and the actinides are not
Generally speaking, the lanthanides are naturally occurring and stable, although relatively uncommon. The actinides are naturally occurring through uranium; after that, they're synthetic, and all are unstable (radioactive.)
Actinides and lanthanides lose electrons and form cations.
Lanthanides and Actinides are placed separately as the properties of these elements is quite different from the elements in periodic table.
Rare Earth elements or lanthanides are placed in the period 6 of the periodic table of Mendeleev. Actinoids are placed in the period 7 of the periodic table of Mendeleev.

describe the complex formation by lanthanides?
The densities of the lanthanides generally have less variability compared to the densities of the actinides. This is because the lanthanides are more similar in size and electronic structure, leading to more consistent densities. In contrast, the actinides exhibit larger variations in density due to differences in atomic structure and electron configurations.
Lanthanides and actinides occupy period 6 and 7, respectively, due to their electron configurations. Lanthanides have their outermost electrons in the 5d sublevel, which fills in period 6, while actinides have their outermost electrons in the 5f sublevel, which fills in period 7. This results in their placement in these periods of the periodic table.
There are 15 lanthanides (from lanthanum to lutetium) and 15 actinides (from actinium to lawrencium) in the periodic table. These elements belong to the f-block of the periodic table and have unique properties due to their electron configurations.
