The basic metals are similar to transition metals but tend to be softer and to hint at nonmetallic properties. What are some characteristics of the Boron Family? They are 14 elements which have similar properties. The lanthanides are also occasionally referred to the rare earth elements. The lanthanide series consists of the 14 elements, with atomic numbers 58 through 71, that follow lanthanum on the periodic table of elements. The first 5 d transition element is either lanthanum or lutetium, depending on how you interpret the periodic trends of the elements. Lanthanides and Actinides Lanthanides and actinides are collectively called f-block elements because last electron in them enters into f-orbitals of … rare-earth metals of the lanthanides as well as yttrium, and scandium; however, some transition metals and actinides can also display this effect[2]. These elements are also called inner transition elements. These elements are also called inner transition elements. Sometimes only the lanthanides, and not the actinides, are classified as rare earths. lanthanides and actinides.
