Different metal containing compounds emit colored light when fireworks burn. This colored light is a combination of series of colors called spectral pattern.(谱带) Each element emits its own characteristic spectral pattern, which can be used to identify the element. This allowed the scientists in 1900s to develop models of the atom's internal structure
