periodic table
Modern version of the periodic table of the elements. To learn an element's name, atomic number, electron configuration, atomic weight, and more, select one from the table.
The lanthanoid series (also referred to as the lanthanide series) consists of 15 consecutive chemical elements in the periodic table with atomic numbers 57 through 71. These elements range from lanthanum to lutetium.1
The 15 elements in the series are:
- Lanthanum (57)
- Cerium (58)
- Praseodymium (59)
- Neodymium (60)
- Promethium (61)
- Samarium (62)
- Europium (63)
- Gadolinium (64)
- Terbium (65)
- Dysprosium (66)
- Holmium (67)
- Erbium (68)
- Thulium (69)
- Ytterbium (70)

The International Union of Pure and Applied Chemistry prefers the term "lanthanoid" because the "-ide" suffix is typically reserved for negatively charged ions, though "lanthanide" remains the more common term in general usage.1
