Objectives The objectives of this lab are to: a) Perform flame tests of metal cations in order to observe their characteristic colors, b) Match the flame colors observed to an appropriate wavelength of visible light, and then perform calculations to determine the frequency and energy of the emitted photons, c) Relate these results to the types of electronic transitions occurring in these elements, d) Practice writing electron configurations for these (and other) elements.

Metal is an element that can emit a color when they are heated or burned. Flame colors are produced from the movement of the electrons in the metal ions present in the compounds. When the metals are heated, the electrons gain energy and can be excited into any of the empty higher-energy orbitals, depending on the amount of energy a particular electron happens to absorb from the flame. Because the electron is now at a higher and more energetically unstable level, it falls back down to the original level, but not necessarily in one transition. Each of these jumps involves a specific amount of energy emitted as light energy, and each corresponds to a particular color. As a result of these transitions, a spectrum of colored lines is produced. The color detected is a combination of all the individual colors. The exact energy differences of the possible transitions vary from one metal ion to another; therefore, each unique ion has a different pattern of spectral lines, creating a different flame color.

In the present study we report the construction of a simple atomic emission spectrophotometer and we describe its computer interface and its calibration procedure. The final instrument is employed for the detection of the presence of metal ions in commercially available drugs. The cost of the whole construction is low and it can be readily applied within the secondary education chemistry curricula in order to strengthen students’ engagement and understanding of a modern analytical technique that is based on the well known flame tests.

The present laboratory work based in the preparation of fire started is proposed as an alternative in the teaching of chemistry for students of high school, with the purpose of articulate and integrate the abilities of students from the knowledge acquired. In this sense, is proposed the progression of learning, so that students develop from a specific concept towards the understanding of a phenomenon through a concrete and accessible teaching practice that assure that interaction. This practice allowed consolidating and expanding the teaching-learning process. Based on the interest in the topic propounded, the students were able to internalize the knowledge, reaching a satisfactory theoretical-practical relationship.
