would an emission spectrum of an unknown sample be a good way to qualitatively identify which elements are present?


What information would you look for in an emission spectrum to allow you to determine quantitative information? In other words, how could you tell how much of a certain element was present?

Answer #1

Yes, emission spectrum is a good way to qualitatively identify which elements are present because it examine wavelength of photons emitted by atom (from the element) during their transition from an exited energy state to a lower energy state. Each element emit a characteristic wavelength which is used to identify the element.

To determine quantitative information we will study the intensity of emitted radiation which is proportional to the number of atoms of the element.
