Answer:

Alpha Particles:

  • Slow and heavy
  • Low penetrating power (can be stopped with a sheet of paper)
  • Large charge (ionize electrons from atoms strongly)
  • Have two protons and neutrons

Beta Particles:

  • Fast and light
  • Medium penetrating power (can be stopped with aluminum or plastics)
  • Charge not as strong as alpha particles (they ionize atoms that they pass by)
  • Same mass and charge as electrons
