The term "lithium" comes from the Greek word "lithos," meaning "stone," reflecting its discovery in minerals. It was first identified in 1817 by Swedish chemist Johan August Arfwedson in petalite, a lithium-bearing mineral. Lithium was historically significant due to its use in various applications, including medicine for treating mood disorders and in batteries, though its broader industrial applications were recognized later. The name emphasizes its mineral origin and early association with geological formations.
