Atoms Release Light: When an atom is struck by electricity (or heat), it gains some energy. This excites an electron and causes it to jump from its normal energy level to a higher level. The electron then falls back down to its original state and releases some energy in the form of light. One example from science class is the flame test where atoms are heated in a bunsen burner flame and they release light. Each type of atom releases a different colour.
