Elements found in the earths crust are called rare earth metals, and lanthanide elements are good examples of these. Lets step back in time a moment - to the year 1787 in Ytterby, Sweden, to be ...

Lanthanides - body, used, water, Earth, chemical, form ...

The other lanthanides are relatively abundant in Earths crust. Cerium, for example, is the twenty-sixth most abundant element. Even thulium, the second rarest lanthanide after promethium, is more abundant than iodine. The point of interest about the lanthanides, then, is not that they are so rare, but that they are so much alike.

Lanthanides source : Lanthanides-The elements in which the last electron enters in (n-2)f orbitals are called f-block elements . In these elements last electron is added to the (third to the outer most shell) ante penultimate shell.They are also called inner transition elements.

Lanthanides and Actinides | Introduction to Chemistry

The lanthanides and actinides form a group that appears almost disconnected from the rest of the periodic table. This is the f block of elements, known as the inner transition series. This is due to the proper numerical position between Groups 2 and 3 of the transition metals.

Actinide - Wikipedia
