Atomic Emission Spectra Comparison – Years 11–12
Students compare representative emission-line spectra for multiple elements and investigate how discrete atomic energy transitions produce characteristic spectral fingerprints. Comparing elements side by side supports discussion of how spectroscopy is used to identify substances. The full interactive is available to licensed Education Universe users.
Years 11–12, UndergraduateExplorer
Learning outcomes
- Explain how discrete energy transitions produce emission lines.
- Compare the emission spectra of different elements.
- Explain how spectra can be used to identify an element.
Teaching guidance
Give students an unlabelled spectrum and ask them to identify the element by comparing line positions before revealing the answer.
