lanthanide
Periodic table fifteen
A lanthanide is any of fifteen metallic elements with atomic numbers 57 through 71, from lanthanum to lutetium.
These elements share similar chemical properties and appear together in the periodic table, often grouped with the actinides as rare earth elements.
Lanthanides are used in magnets, lasers, and electronic displays.
