So I always wondered if the name of "lithium" implies it has some kind of historical connection to "lithuania". But I looked it up and it doesn't. The two aren't even etymologically related. "Lithuania" comes from Latin "litus" for "shore" (think "littoral") and "Lithium" is from greek "lithion" for "stone" ("monolith").
EDIT: Wiktionary disagrees on Litus and claims Lithuania is either from proto-Slavic and cognate with "Latvia"; or named after a river. Still not Greek. https://en.wiktionary.org/wiki/Lithuania
