2. Unit 3-6 Nuclear Fusion vs. Fission

3. Explaining Mass Defect
E=mc2 says that mass can be converted into energy when the nucleus is formed
Sun is about 109 times the diameter of Earth, and 1.3 million planet Earths can fit inside the Sun

4. Nuclear Fusion
When multiple nuclei smash into each other forming a larger nucleus.
Hydrogen is the fuel for H-bomb and our sun
- birth of otta octavius

5. Nuclear Fusion Equations

6. Nuclear Fission
A large nucleus is split into two or more smaller nuclei (process sped up by hitting it with a neutron)
Releases Alpha, Beta, Gamma Rays and a lot of energy
– nuclear bomb compilation
- explanation of fusion
- Used to power nuclear weapons (atomic bombs), nuclear subs, & nuclear power plants

7. "Little Boy" was dropped on the city of Hiroshima 970lbs yields 15kt of TNT 141lbs of uranium, followed seventy-six hours later on August 9 by the detonation of the "Fat Man" nuclear bomb over Nagasaki 10,600 pounds plutonium grade (4.7 kiloton) 14 lbs of plutonium and only about 2lbs fissioned

- hydrogen bomb history video after atomic bomb WWII

8. Nuclear Power Plant
Clean power
Need water to cool down the reactor

9. Nuclear Fission
Chernobyl power plant

10. Nuclear Fission
Fukushima

11. Chemistry Cat!

12. Assignments Summary - What are the pros and cons of nuclear power?
Lab making heat due next class
Clean up procedure: scrape the remain inside the petri dish in the trash can, then rinse

13. Fission vs. Fusion
Fission: splitting of the nucleus into smaller fragments
Think of the domino effect; atomic bomb
U slow moving 10 n  smaller atoms + more slow moving 10 n + a lot of energy
Fusion: combining of the nuclei to produce a greater nucleus
Think of the sun; hydrogen bomb
4 11 H e  42 He + energy

14. Online Lab 1 laptop per group
Click “Play”, “Later”, “Run”
Find the secret function in the “Chain Reaction” tab that let you make an atomic bomb
