Flame Test Lab - Mr. Eagen''s Science Classroom
By placing atoms of a metal into a flame, electrons can be induced to absorb energy and jump to an excited energy state, a quantum jump. They then return to their ground state by emitting a photon of light (the law of conservation of energy indies that the photon emitted will contain the same amount of energy as that absorbed in the quantum jump).

If you use a pure metal powder and observe a color spectrum, it is clearly due to the metal atoms as there is nothing else. The question that you are asking comes into play when you use a metallic salt, which upon heating disassociates into metal ions and nonmetalic anion atoms or groups.
Introduction Salt slurries in petri dishes with methanol are ignited and characteristic colors for various metals are observed. Colors of emission spectra are due to loosely-bound valence electrons being excited in a flame and dropping back down while emitting light.
