Lesson Plan: Atomic Emission Spectroscopy Chemistry
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to explain the emission of fixed colors of light by metal atoms and use line spectra in identifying elements.
Objectives
Students will be able to
- explain the production of atomic emission spectra and what happens to a sample during the process,
- know in simple terms that a line emission spectrum results from electrons relaxing from a higher energy level to a lower one and emitting radiation,
- explain the use of line emission spectra to identify elements,
- compare line emission spectra to identify the elements in a sample,
- use atomic emission spectroscopy to determine the concentration of metal ions,
- compare atomic emission spectroscopy, particularly flame emission spectroscopy, with flame tests,
- use data from a flame photometer to determine the identity or concentration of ions in a dilute solution.
Prerequisites
Students should already be familiar with
- electron shells,
- flame tests.
Exclusions
Students will not cover
- named series such as Lyman and Bulmer,
- quantitative descriptions of emission spectroscopy, for example, transition energies or energy levels.
