       • The Alkali Metals
         • reaction with water
           • lithium
             • Fizzed, crimson red flame
           • sodium
             • fizzed, melted, yellow-orange flame
           • potassium
             • fizzed, caught fire, exploded! lilac flame
         • stored in oil because they react with oxygen and water very quickly
