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.
This chemical element is promethium (Pm).
Erbium (atomic number 68). It is an example of lanthanide.
Because all lanthanide's have almost similar physical as well as chemical properties.
The lanthanide, or lanthanoid, series. This is a classification on the periodic table characterized by shared properties of these elements, for example, Holmium and Praseodymium have similar properties. Lanthanide is prefered by the public, lanthanoid is preferred by scientists of IUPAC (International Union of Pure and Applied Chemistry).

No. Americium is an actinide.
Yes, lanthanide and Actinides are transition elements and they are specifically called inner transition elements.
Neodymium is a lanthanide.
