Atomic Spectra: Light, Energy and Electron Structure—ChemTopic™ Lab Activity

firewatch

Just as white light can be separated into the visible spectrum, when a pure atomic gas is subjected to a high-voltage electrical discharge, light is produced and the gas glows with an atomic emission spectrum unique to that element. With the Atomic Spectra: Light, Energy and Electron Structure—ChemTopic™ Lab Activity, learn to recognize continuous versus line emission spectra for light sources using a spectroscope, and use the spectroscope to observe the atomic spectra of different elements and identify elements present in a variety of light sources.

Concepts

  • Atomic Emission Spectrum
  • Electron Energy Levels
  • Quantization of Energy
  • Electron Transitions
