CER: How Electrons Produce Light and Color

In this assignment, you will use the CER (Claim, Evidence, Reasoning) format to explain how electrons absorb and release energy, and how this process is responsible for the colors we see. Be sure to answer each part in complete sentences and use scientific vocabulary where appropriate.

Use your knowledge of atomic structure and electron behavior to answer the following prompt using the CER format.

Explain, using the CER (Claim, Evidence, Reasoning) format, how electrons absorb energy to move from the ground state to the excited state, and how they release energy as light when returning to the ground state. In your explanation, describe how this process is responsible for the colors we see. Be sure to include:

• A clear claim about how electrons absorb and release energy.
• Evidence from class, labs, or readings that supports your claim (such as observations of flame tests or emission spectra).
• Reasoning that connects your evidence to your claim, explaining how the movement of electrons produces different colors of light.
