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

Page 4: Why is Water Greenish Blue?

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?
