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.
