Flame tests can be used to identify an element. Each element emits characteristic waves of light when it is heated in a flame. What describes how the light is produced?

• Protons in the ground state lose energy and give off light.

• Protons in the ground state gain energy and are emitted from the nucleus, giving off light.

• Electrons in the ground state lose energy and move to an excited state, giving off light.

• Electrons in the ground state gain energy, move to an excited state, and give off light when they return to the ground state.
