Pronunciation
- (Southern-England) audio
- /ˈlænθənaɪd/
- lăn'thənīd
Etymology
From lanthanium + -ide.
Meanings
- Any of the 15 rare earth elements from lanthanum to lutetium in the periodic table; because their outermost orbitals are not filled, they have very similar chemistry; below them are the actinides.
- Any of the 14 rare earth elements from lanthanum to ytterbium (lutetium is excluded by some authors as it is a d-block rather than an f-block element).
- (dated) Any of the 14 rare earth elements from cerium to lutetium (lanthanum having been excluded because it was thought to be a d-block element in the past).
