Because all lanthanide's have almost similar physical as well as chemical properties.
Periodic table would be complex then. It will make study of elements difficult.

The ability of a microscope to measure by separation images that would be difficult to see with the naked eye. This separation is called angular separation.
Er: Erbium
its in the Lanthanide series
No. Americium is an actinide.
Noar schiniminoar
Yes, lanthanide and Actinides are transition elements and they are specifically called inner transition elements.
Because of the lanthanide content
f1 to f14
