Lithium’s story begins in Greek: lithos meant “a stone.” Stone, since the element was discovered in a mineral rather than plant sources like related elements. It reached English by 1818 as lithium. Coined by chemists to distinguish the mineral-derived alkali metal. Today, lithium means a soft, light, silvery-white metallic element used in batteries and medicine.
