The lanthanide series consists of the 14 elements, with atomic numbers 58 through 71, that follow lanthanum on the periodic table of elements. These 14, along with the actinides—atomic numbers 90 through 103—are set aside from the periodic table due to similarities in properties that define each group.Click to see full answer. Similarly, what elements are in the lanthanide series?The series always includes the 14 elements with atomic numbers 58 through 71, which are (in order of increasing atomic number) cerium , praseodymium , neodymium , promethium , samarium , europium , gadolinium , terbium , dysprosium , holmium , erbium , thulium , ytterbium , and lutetium .Beside above, is lanthanum a lanthanide? Elements Lanthanum (57) through Lutetium (71) on the periodic table are considered to be Lanthanides. Thereof, why there are 14 elements in lanthanide series? In the lanthanide series, we have 14 elements that result from the addition of electrons into the f orbitals. For the lanthanide series, the electron configurations are 4f (1-14). The lanthanides form compounds that are primarily ionic in character, with coordination numbers of 8 or 9.How many lanthanides and actinides are there?There are thirty total elements in the lanthanides and actinides. They are often called the “inner transition metals.” The lanthanides are the elements with atomic numbers from 57 to 71. These 15 metals (along with scandium and yttrium) are often called the rare earth elements.
