Yttrium, scandium, and the 15 lanthanides are sometimes referred to collectively as rare earth elements although they may be mostly ignored. Key points the lanthanide and actinide series make up the inner transition metals the lanthanide series includes elements 58 to 71, which fill their 4f sublevel. The lanthanides (or rare-earth elements) and actinides are two families that are related because they both result from electrons being added into an f sub-level.
