Groups I & II Flame Tests

  • If elements are heated up, they absorb specific wavelengths of electromagnetic radiation thus giving a characteristic absorption spectrum
  • The element then emits the same specific wavelengths giving an emission spectrum
  • If these wavelengths are in the visible region they can be viewed through a diffraction grating or prism as coloured lines.
