Lithium

Lithium is a soft silver-white metal (when the surface is freshly cut) and belongs to the alkaline group of elements within the periodic table. Lithium is not naturally found in its metallic state as metallic lithium is far too reactive. Lithium metal is extracted from mined Lithium-Salts through an electrolyses method to reduce the lithium containing salt to lithium metal; the extracted lithium metal is then stored in dry conditions, typically under mineral oil, to prevent the humidity in air from reacting with the lithium and forming lithium hydroxide (LiHO).
