  1. Nuclear Decay Come together, fall apart

  2. Before we Begin….. • What is Half-Life? • What is the difference between fission and fusion?

  3. Tell me the mass • Carbon 14 • Carbon 12 • Nitrogen 14 Uranium 238 Uranium 232

  4. Real Quick • What does the Atomic Number tell us?

  5. Real Quick • What does the Atomic Number tell us? • THE NUMBER OF PROTONS IN THE NUCLEUS

  6. Put it together • Carbon 14 has a mass of ________

  7. Put it together • Carbon 14 has a mass of ___14____

  8. Put it together • Carbon 14 has a mass of ___14____ C 14

  9. Put it together • Carbon 14 has a mass of ___14____ C 14

  10. Put it together • Carbon 14 has a mass of ___14____ C 14 6

  11. Come to the board • Uranium 238 Carbon 12 Calcium 455

  12. Alpha and Beta Decay • Alpha – The removal of a Helium Particle. Beta – The removal of an electron particle of from a Neutron.

  13. Alpha decay

  14. Beta Decay Did the mass change???

  15. Lets try an equation • ALPHA DECAY – what do we know is going to happen?

  16. Uranium 235 (alpha decay)

  17. Beta Decay • Beta decay is the removal of __________.

  18. Carbon 14 (beta decay)

  19. Mendelevium 257 (alpha decay)

  20. Calcium 45 (beta decay)

  21. The Smallest Week of the Year • Monday – Finish up Radioactive Decay. Positron Decay and Gamma Radiation. • Tuesday – Quiz (Take it easy, you guys know this)**NO MUCA MEETING THIS WEEK**

  22. Recap

  23. Recap – Beta Decay

  24. The last three decays • Positron Decay – A proton losing a POSITIVE ELCTRON and turning into a Neutron • **THE PROTON COUNT GOES DOWN!!!

  25. Positron Decay

  26. Positron Decay

  27. Gamma Ray • Gamma Radiation – Beta Decay with a y-ray

  28. Röntgen radiation • Röntgen radiation – The X-Ray THERE IS NO EQUATION FOR X-RAY ALL YOU NEED TO KNOW IS THAT Röntgen discovered it

  29. Fluorine 19 (positron decay)

  30. Mendelevium 257 (Gamma Radiation)

  31. Calcium 45 (positron decay)

  32. Uranium 238 (gamma Radiation)

  33. Nitrogen 13 (Positron Decay)

  34. Cobalt 60 (gamma Radiation)
