Sodium (Na)
By: LaRoyce Gant and Jessica Fierro
Information
Sodium was first discovered by Sir Humphry Davy in 1807. He used electrolysis of caustic soda to bring out the true form of Sodium. Sodium is a soft, bright, silvery metal that floats on water. Sodium is found in sulfate chloride carbonate. The melting point for Sodium is 97.5 degrees Celsius and the boiling point for Sodium is 883 degrees Celsius. The density is 0.97 g./cm. at 20 degrees Celsius. Sodium is used Baking Soda, Salt and Sodium Vapor street lights?? It is the sixth most abundant metal in the Earth's crust. Also it is a vital element for living organisms.
