During a flame test, ions of a specific metal are heated in the flame of agas burner. a characteristic color of light is emitted by these ions inthe flame when the electrons(1) gain energy as they return to lower energy levels(2) gain energy as they move to higher energy levels(3) emit energy as they return to lower energy levels(4) emit energy as they move to higher energy levels

Answer;

-Emit energy as they return to lower energy levels.

Explanation;

-A characteristic color of light is emitted by these ions in the flame when the electrons emit energy as they return to lower energy levels.

-The metal ions do absorb energy, and the electrons are boosted to higher energy levels, but they emit that energy as they fall to lower levels, and it is the photons of light they are emitting that can be seen.

water is used to store them because it would keep the radiation from getting out in the open and causing harm to the workers
