Sodium or sodium is a chemical element in the periodic table that has the symbol Na and atomic number 11. Sodium is a reactive metal which is soft, silvery, and like a candle, which belongs to the alkali metals are widely available in natural compounds (especially halite ). He's very reactive, yellow flame, oxidizes in the air, and reacts strongly with water, so it must be stored in oil. Because highly reactive, sodium almost never found in the form of the element of pure.
The main properties
Like the other alkali metals, sodium is a reactive element that is soft, light, and silvery white, which never form a pure element in nature. Sodium floats on water, decompose it into hydrogen gas and hydroxide ions. If crushed into a powder, sodium will explode in water spontaneously. However, he usually does not explode in the air temperature below 388 K.Sodium also when in a state of OH-ions bind to it will form a strong base is NaOH.
