Rare earth metal: Any of a large class of chemical elements including scandium (atomic number 21), yttrium (39), and the 15 elements from 57 (lanthanum) to 71.

稀土金属：一个化学元素大家族中的任何一种，包括钪(原子序21)、钇(原子序39)以及从57号元素(镧)到71号元素。

Exactly what is a rare earth metal is very slightly arguable, some would say it is only the lanthanides, lanthanum, cerium through to lutetium in that little box at the bottom of the periodic table.
