Question
The dazzling colors produced by fireworks result from excited gaseous atoms or molecules emitting light. The normal
electron configuration of an atom is known as the "ground state." In ground state, all electrons are in the lowest energy
levels available. When atoms or ions are heated, some electrons may absorb enough energy to allow them to "jump" to
higher energy levels. The atom or ion is then said to be in the "excited state." The electrons cannot remain in this excited
state for long and will emit energy in the form of light when they return to ground state. It is this light we see when an
atom is heated in a flame. The frequency or color of light emitted depends on the energy difference between the excited
state and the ground state.
