... In fact, the discrete lines in the spectra must mean that electrons in atoms can only exist at specific energy levels, and the spectral lines represent transitions between these levels. When an atom is excited electrons are sent to a higher energy level. From there, the electron drops back to the gr ...

Module 1 - Identifying Metals Using Atomic Emission
... Students will learn how applying a flame to a metal solution can produce a distinct color of light. Chemists use this technique to determine the quantity of various metals contained in a sample. Introduction: The electrons in an atom occupy different energy levels. At the lowest possible energy ...

Practical Laboratory #2: Emission Spectra 2
... Do the following steps for the unknown light source after you’ve set it up: 1. Start data collection on the Logger Pro software. An emission spectrum will be graphed. 2. When you achieve a satisfactory graph, stop data collection. If the highest peak in the emission spectrum is > 1, then the sensor ...
