Flame color for metal ions

Why do different metal ions release different colors of light?

WebLithium's valence electron energy level is 2, and it creates a red pinkish color. Barium , with a valence electron energy level of 6, creates a light green flame color. Potassium on the other hand, with a valence electron energy level of 4, burns a purple color, meaning that it has a high frequency. WebFlame Test Activities Introduction The purpose of the flame test lab is to understand qualitative chemical analysis and the concept of light emission from a quantum transition.
