How does it work? Answer in the space provided. Flame Test Lab Objective In this lab students will learn about atomic energy levels, emission spectroscopy, and flame tests for element identification. Compared to the other metals studied, did the radiation emitted by this metal cation have. FLAME TEST LAB PROCEDURE. This one color results from a combination of all lines of the emission spectrum, in proportion to their intensities. Do you think your observation is related to the type of light emission you saw in the lab? It was important to use a different wood splint for each test because the wood splint was contaminated by the prior element which would have effected the color of the element being tested. Since the energies of . The flame was orange at the end of each test because the wood splint started burning. 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. 2019 0925132351399 - shows the actual lab and the answer are on loose-leaf, good luck !
