Nuclear Reactions_3

1. fission

   • atomic bomb
   • little bit of mass is converted into energy

2. fusion

   • Sun
   • fusion reactor
     • nuclear fission happens at the center of the Sun
   • nuclei split into smaller pieces

3. radioactive decay

   • radiation therapy
     • treat cancer
   • Radioactivity
     • alpha
       • beta
         • gamma
           • high light energy
         • electron - moving very fast, stopped by thin sheet of metal
       • particles composed of 2 protons and 2 electrons
     • Units of Radiation
       • RAD
       • REM

4. subatomic particles

   • electrons
     • Neg. charge
   • protons
     • positive charge
   • neutrons
     • neutral, has no electrical charge

5. Atom

   • electron cloud, contains a nucleus
     • Nucleus
       • Protons
       • Neutrons
       • Electrons (outside of the Nucleus,takes up a lot of space, hardly any mass, tiny).

6. EMC2

   • tells how much energy is created when mass is converted into energy via fission/fussion

7. isotope

   • No. of protons and neutrons in the nucleus
