SmartBoard Exercise
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?
High Energy Excited State
Do Atoms Have Specific Colors?
