Line Spectrums

Line Spectrums

1. Some Elements emit distinctive colours when heated

   • Lithium = Red flame
   • Sodium yellow/orange flame
   • Potassium lilac flame

2. Each Elememt goves a characteristic Line Spectrum

   • When an element is heated the electroms become excited and release energy as light, the wavelengths emitteed can be seen as a line spectrum each line spectrum is unique as every element has a different electron arrangment

3. Line Spectrums can Help identify new elements

   • Caesium and Rubidium both discovered by their line spectrums
