SUMMARY
Flame tests specifically identify metals by observing the characteristic colors emitted when heated, due to the excitation of electrons in metal atoms. The discussion clarifies that the anion component of ionic compounds typically does not influence the flame color because most anions do not emit visible light. This phenomenon is not coincidental; it is a result of the electronic structure of metals compared to anions. Thus, flame tests are reliable for identifying metal ions but not for determining the presence of anions.
