The unique color that is observed during a flame test is actually a mixture of several different wavelengths of visible light. Well, when an atom or ion absorbs energy, its electrons can make transitions from lower energy levels to higher energy levels. In this experiment, the metal cations in the solutions were initially in the (ground, excited) state. Flame tests are used to identify the presence of a relatively small number of metal ions in a compound. To the bare eye, when a component is vaporized in a flame or {an electrical} discharge the emission.
