About Lithium

Named after the Greek word meaning stone, Lithium is a soft metal, with the lowest density of all metals in the Periodic Table. Therefore, it can be quite easily cut with a knife and is almost as light as wood. Lithium does not occur in its pure form in nature but can be found in a number of minerals. Lithium is toxic; it is an alkali metal which easily reacts with water producing lithium hydroxide, used as an agent to absorb carbon dioxide. A very important usage if lithium is in batteries, especially rechargeable ones for our modern communication devices. For a variety of usages, lithium is alloyed with the metals like aluminum, magnesium, and other metals.
