flame tests and emission spectra lab answers

This experiment will help one understand how a flame test is performed and that every metal has a unique bright line spectra. This information can be used to identify elements in space to tell whether a planet has oxygen on it or not. In this lab students will learn about atomic energy levels, emission spectroscopy, and flame tests for element identification. FLAME TEST AND ATOMIC SPECTRA LAB the emission spectrum of an unknown source, we can compare the colors of its spectral lines to known spectral lines we see in a laboratory, and tell which substance matches. Unfortunately, techniques more sophisticated than those used in this lab are required to obtain such line spectra. To the naked eye, when an element is vaporized in a flame (or an electrical discharge) the emission spectrum will appear to be just one color. 2. Having read this much, please answer the first three questions, and write your answer in the space provided on your report sheet. c) Relate these results to the types of electronic transitions occurring in these elements. This means a bright line spectra can be used to identify any element. Calculate the energy of emitted photons. Perform a flame test to identify the characteristic color of metal ions. The emission of energy in the visible portion of the spectrum as those electrons return to lower energy levels. Continuous Line Continuous First Spectrum Line Color Red Red Red First Spectrum Line Number 6.9 6.4 6.8 Second Spectrum Line Color Orange Red-Orange Orange Second Spectrum Line Number 6 6.2 6.2 Third Spectrum Line Color Yellow ... Atomic Emission and Flame Test Lab 3.pdf. 524 final exam keiderling. 3. Which method would be better for you to implement to identify unknown elements present in a substance: using a series of flame tests or analyzing the emission spectra? Identify the metal ion in an unknown solution. atomic emission spectroscopy lab answers dorith de. flame test and atomic spectra lab.
