  1. NUCLEAR CHEMISTRY

  2. Strong nuclear force---holds the nucleus together (overcomes proton repulsion) • Electrostatic force—attractive force between protons and electrons (holds entire atom together)

  3. 2 reasons why something is radioactive? • Past atomic # 83 • An isotope (Ex: C—14)

  4. 3 radioactive particles • Alpha—a helium nucleus; least penetrating power • Beta—a high energy electron • Gamma---most penetrating; pure energy

  5. 1. Why is cobalt—60 radioactive? • 2. Why is Francium radioactive? • 3. What force holds the entire atom together? • 4. What force holds the nucleus together? • 5. Write the nuclear equation for the alpha decay of Polonium. • 6. Write the nuclear equation for the beta decay of Bk—249.

  6. Pass the Ball—nuclear review • 1. Give 1 difference between chemical vs. nuclear reactions. • 2. Give another difference. • 3. Give 1 reason why something is radioactive. • 4. Give another reason for radioactivity. • 5. Name the 3 radioactive particles in order of increasing penetration. • 6. Which radioactive particle decreases atomic number by 2 and mass by 4? • 7. Which radioactive particle increases atomic number by 1 and does not change mass? • 8. Which force holds the atom’s nucleus together? • 9. Which force holds the entire atom together through the force of attraction between protons and electrons? • 10. What’s the difference between fission and fusion?
