There are multiple numbers on the periodic table. The ones right under the abbreviations is the atomic weight of the atom. The number just above the abbreviation is the atomic number. Here is an example: Sodium 11= Atomic Number Na= Atom Abbreviation 22.99= Atomic weight
The lanthanides are located in the f-block of the periodic table, specifically in the sixth period between barium (56) and hafnium (72). They are also known as the rare earth elements and have atomic numbers ranging from 57 to 71.

they are mostly classed as metals because most of the periodic table is classed as metals.
