Answer:

The correct answer is metal.

Explanation:

The flame test is an analytical method used in chemistry to detect the presence of certain elements, mainly metal ions, based on the characteristic emission spectrum of each element. The color of the flame can also depend on temperature, identify the unknown element or simply a metallic ion based on its characteristics when emitting light.

Metallic ion because the metallic ions will enter an exited state and release photons energy, in the form of light, as they return to their ground state.
