The Atomic Color Code
• Fireworks generate a noticeable amount of heat and light
• The colors produced are from heating metal salts like calcium chloride or sodium nitrate
• Atoms of each element absorb energy and release a specific color of light
The atom’s outer electrons absorb energy and step up to an excited higher energy level
This only lasts a brief time.The electron sheds that excess
energy in the form of light and moves back to it’s lower energy level
How Do the Atoms Emit Light?
