Sydney Schell October 18th‚ 2012 Identifying Metallic Components Introduction: Spectroscopy is the study of the electromagnetic radiation emitted or absorbed by the atoms and molecules. A photon in short is light. Atoms produce light by putting energy in‚ the electron then becomes excited and goes up an energy level‚ the electron then falls back down to its ground state‚ and out comes a photon (light). The electromagnetic spectrum contains color that we can and cannot see. The color blue has

ions‚ based on each element’s characteristic emission spectrum” (Flame Test 1). Using this test‚ an element can be identified using its emission spectrum‚ or color. An emission spectrum is defined as the spectrum of frequencies of electromagnetic radiation emitted due to an atom’s electrons making a transition from a high energy state to a lower energy state. Since each element has different numbers of electrons‚ each element’s emission spectrum is different. This allows elements to be identified by

Lab #4 Emission Spectroscopy and Flame Test Date of Lab: 10/24/13 OBJECTIVE To observe a continuous spectrum‚ emission spectrum‚ and an absorption spectrum‚ and be able to distinguish among the three. To be able to identify metal ions by doing a flame test and looking at a spectrum. At the same time increasing the ability to use and understanding of lab equipment‚ in this case‚ a spectroscope. To be able to calculate the frequency and energy of certain frequencies of light. PROCEDURE

Introduction: Every element and subsequent atom associated emits light; also know as electromagnetic radiation‚ when in an excited state. Analyzing this emitted light can give insight to the makeup and characteristics of them. The light given off by an energetically excited atom is not a continuous distribution of all possible wavelengths‚ but rather consists
