Spectral Lines, Atomic Emissions Lab Activity

In this lab, your students will use a spectroscope and read spectral lines to identify elements by their atomic emission from exciting electrons. A simple to use quantum chemistry lab.

WHO IS IT FOR?

This flame test lab is perfect for first year chemistry students.

HOW TO USE IT

• Present three different spectral tubes to your students. Either tell them the identity of the element, or have them research based on the spectral line measurements.
• Present students with a fourth spectral tube, keeping its identity unknown. I like for this to be a repeat of one of the first three elements.
• I use this after my flame test lab so students can see the spectral lines as a better alternative to the flame test.

FEATURES

• Engaging
• Inquiry activity
• Written conclusion to synthesize thoughts
• Post lab questions to help guide students through concept

WHAT MATERIALS ARE REQUIRED?

• Spectral tube power supply
• Spectral tube gas samples (at least three)
• Spectroscopes with measurements
• Dark room

WHAT’S INCLUDED

• Lab activity: post lab questions and a written conclusion
• "How to Write a Chemistry Lab Report"
