Light Emissions
The diagram to the right shows 4
possible electron emissions. Use the
questions.

released in the diagram? How
do you know?
2. There are four wavelengths
present in the diagram: violet,
blue, green, and red. Which
atom represents each color?
3. Explain the difference between
an atom in its ground state
and an atom in its excited
state.
