This project involves performing flame tests to identify various metal ions by the characteristic colors they emit when heated. Students will learn about the relationship between energy levels and electron transitions in elements.
Different metal ions will produce distinct flame colors due to their unique electron configurations.

Put on safety goggles and ensure the workspace is safe.
Clean the wire loop with a flame to avoid contamination.
Dip the wire loop into the first metal salt sample.
Place the loop in the flame of the Bunsen burner.
Observe and record the color of the flame.
Repeat steps 3-5 for each metal salt sample.
Compare the observed flame colors with known colors from a reference chart.
Discuss the results and identify each metal based on its flame color.
Each metal ion will produce a specific flame color, helping to identify the metal based on its characteristic emission spectrum.

Use caution when handling flames and metal salts. Wear goggles throughout the experiment.
Display a color chart of flame tests for reference.
Show images or videos of flame tests.
Explain the science behind flame colors.
Discuss applications in real-world chemistry.
Each metal has a unique electron configuration, which emits different wavelengths of light when excited.
When performed with safety precautions, flame tests are generally safe.
No, some metals may produce similar colors or require more advanced techniques.
