StoichiometryL.docx; Marquette University; CHEMISTRY; CHEM 1001 - Spring 2014; Register Now. Since each atom has many excited states (high energy levels) available to it, several colors of light can be emitted by each element. Progress % Practice Now. Santa Monica College Chemistry 11 Atomic Emission Spectra Page 1 of 6 Atomic Emission Spectra Objectives The objectives of this laboratory are as follows: • To build and calibrate a simple box spectroscope capable of measuring wavelengths of visible light. Atoms become excited when they absorb energy; they then emit energy in the form of light as they return to a less excited state. Subpages (2): … 1 Part of this lab is a modified version of "Atomic Spectroscopy" In Experimental Chemistry by James Hall, Houghton Mifflin Co., Boston 1997. Atomic absorption spectroscopy (AAS) and atomic emission spectroscopy (AES) is a spectroanalytical procedure for the quantitative determination of chemical elements using the absorption of optical radiation (light) by free atoms in the gaseous state.Atomic absorption spectroscopy is based on absorption of light by free metallic ions. explanation for the discrete atomic lines became clear.
