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 lanthanide and actinide series. Trait of lanthanide: Lanthanum, element 57. Trait of actinide: actinium, element 89.
Thulium is an lanthanide element with atomic number 69.
It is a lanthanide in period 6.

No. Americium is an actinide.
Yes, lanthanide and Actinides are transition elements and they are specifically called inner transition elements.
The smallest atomic number and atomic weight for a lanthanide is lanthanum itself, element 57. The smallest atomic size is lutecium element 71; the lanthanides steadily decrease in atomic radius through the series, and the smallest is the last of them.
Neodymium is a lanthanide.

Separation of transition metals is difficult. They have similar size, occur together and difficult to separate.
Yes, lanthanide salts dissociate in water to form lanthanide ions and their corresponding anions. This process is similar to the dissociation of other salts in water, where the cation and anion separate due to the interactions with water molecules.
