2. What stage comes first in the process?

  • Ionisation
  • Vapourisation
  • Acceleration
  • Deflection

3. A current is produced when the ion hits the plate. The more hits the..?

  • More lines are drawn
  • Clearer the results
  • Bigger the current
  • Stronger the line on graph

4. How are ions accelerated?

  • Pushed by electricity
  • Shot by the electron gun
  • + ions attracted to - plates; pass through slits between plates
  • Propelled by kinetic energy

5. What does acceleration achieve (as well as speed)

  • Separates heavier ions
  • Focuses ions into narrow beam
  • Makes heavier atoms become slower
  • Forces ions around the bend
