Lithium in its pure form is a soft, silver white metal, that tarnishes and oxidizes very rapidly in air and water. It is the lightest of all metals, with a density only about half that of water. Like all alkali metals, lithium reacts easily in water and does not occur freely in nature due to its activity. It is always found bound with one or more other elements or compounds. When placed over a flame, this metal gives off a striking crimson color but when it burns strongly, the flame becomes a brilliant white.
