2.1.2 The Terms 'Rare' and 'Earth'. The name 'Rare Earths' is misleading as the name itself implies an earthen material which is not ubiquitous. To start with the easy part, the word 'earth' was a common denomination for an oxidic material, usually a metal oxide, i.e. a compound of an element with oxygen.

Terbium (Tb), chemical element, a rare-earth metal of the lanthanide series of the periodic table. Terbium is a moderately hard, silvery white metal that is stable in air when in pure form.
