Quizplus · Accepted Answer

When an electron in an atom goes from a higher energy state to a lower energy state, it emits a photon of a specific frequency, corresponding to the difference in energy between the two states. This emission is known as an atomic emission spectrum, which can be used to identify the element or compound present.
