It depends on the Periodic Table. Some have 14 lanthanides and some have 15 lanthanides. Refer to the related link for a Wikipedia article on the lanthanides for more information.
The chemical element with atomic number 57 is Lanthanum (La). It is a Lanthanide, as it is what the rest of the Lanthanides are based on. It has 57 electrons in 6 shells. It is naturally occuring and non-radioactive.
They are called Lanthanoids or the Lanthanide Series.
Cerium belongs to the lanthanide series of chemical elements, which are part of the f-block in the periodic table.
Lanthanides are any of the series of 15 consecutive chemical elements in the periodic table from lanthanum to lutetium (atomic numbers 57 - 71). With scandium and yttrium, they make up the rare earth metals. Their atoms have similar configurations and similar physical and chemical behaviour; the most common valences are 3 and 4.
Neodymium is a solid element at room temperature. It belongs to the lanthanide series of elements and has a silver metallic appearance.

The periodic table contains seven rows of elements. The lanthanide series belongs to row six as elements 57-71. The actinide series belongs to row seven as elements 89-103.
The chemical element of Europium is part of the lanthanide series. The lanthanide series is comprised of metallic elements, these can be referred to as rare earth elements.

True. The lanthanide and actinide series make up the inner transition metals. The lanthanide series includes elements with atomic numbers 57-71 (lanthanides), while the actinide series includes elements with atomic numbers 89-103 (actinides).
