METALS

Lithium (Li), chemical element, lightest of the solid elements. The metal itself—which is soft, white, and lustrous—and several of

its alloys and compounds are produced on an industrial scale. Lithium is a silver-white light metal. Lithium hydroxide is used in batteries for electrical vehicles and mobile phones. Lithium hydroxide is produced from a chemical reaction between lithium carbonate and calcium hydroxide. The biggest lithium producers are Chile, China, Australia and Argentina.
