A lanthanide is one of 15 elements in the 6th period of the periodic table. This group of elements includes all of the members of the f-block, as well as lutetium. All of the members of this group are metals that display extremely similar aqueous chemistry, with each element being stable as a tripositive ion, so the lanthanides are all notoriously difficult to separate from one another. However, they vary greatly as metals: each metal is paramagnetic, but they have a different response to a magnetic field.
Lanthanides are a subset of the rare earth metals, a group which includes scandium and yttrium.
