5.3 Atoms can be identified by the light they emit When we view the light from glowing atoms, we see that the light consists of a number of discrete frequencies rather than a continuous spectrum This is called element' s atomic spectrum(原子 Btv). In 1800s researchers noted the orderliness of elements atomic spectrum, especially hydrogen, but could not give the explanation
