3. I know what you are thinking.

4. Why neutrinos are the coolest thing you will never see. 1.They are massless. 2.They can travel through anything, unlike light. 3.They were formed 10 -4 seconds after the Big Bang. 4.We are swimming in a sea of neutrinos. 5.THEY MIGHT BE TRAVELING THROUGH TIME.

5. Uh. That can’t be right.

6. AIM: What is radioactive decay? WRITE NOW: Most of what you see around you is empty space. What does this mean?

10. Nuclear Structure Nucleon Protons and Neutrons Nucleon # - Proton # - Neutron # - Nucleon (Mass) Number Atomic Number Chemical Symbol

11. Nuclear Structure Nuclide The name given to a particular species of atom. Isotopes Nuclides with the same number of protons but different numbers of neutrons.

12. What IS radiation? A;glkdj aagda Radiation: A process by which energy is emitted by a body and transmitted in a straight line through matter or space. The sun, nuclear power, microwave ovens, cell phone towers, radio antennas, etc.

13. Radiation - α Where do they come from? Radiation is the emission of particles as a result of nuclear instability.

14. Radiation - α Why?

15. Radiation - α

16. Barium 138 undergoes alpha decay. Write the nuclear formula and determine what the daughter particle is.

17. Β particles are just electrons! Beta decay: neutron splits to become a PROTON and an ELECTRON. Emits a fast moving electron and an “antineutrino” OR a fast moving proton and a “neutrino”

18. Radiation - β

19. Radiation β: Positron Emission

20. Radiation - β Carbon 14 undergoes β decay. Write the nuclear formula and determine what the daughter particle is.

21. Radiation - γ γ rays are just VERY high energy light waves (photons)!

22. Radiation - γ

32. Postulates of Special Relativity 1.The laws of physics are the same in all inertial reference frames. 2.The speed of light is constant in all inertial reference frames. What would you see if you caught up to a light wave?
