  1. Nuclear Chemistry

  2. Hiroshima Nagasaki

  3. Nuclear Fission: splitting of the atom into different parts

  4. Nuclear Fusion:nuclear particles combining releasing energy

  5. How the bomb works Critical mass

  6. How a Nuclear Power Plant works

  7. Nuclear Decay Particles Comes out of the nucleus Alpha: Beta: Positron: Gamma Ray: Neutron: Worksheet: balancing nuclear equations

  8. Half-Life Nuclear Decay Students tear a piece of paper • 1st half life = ½ ½ • 2nd half life = ¼ ¾ • 3rd half life = 1/8 7/8 • 4th half life = 1/16 15/16 Amount of sample gone Amount of sample left

  9. Ws. 1. The half-life of polonium-210 is 138.4 days. How many milligrams of polonium-210 remain after 415.2 days if you start with 2.0 mg of the isotope? 2. Assuming a half-life of 1599 years, how many years will be needed for the decay of 15/16 of a given amount or radium-226?

  10. The half-life of radon-222 is 3.824 days. After what time will one-fourth of a given amount of radon remain? • A sample contains 4.0mg of uranium-238. After 4.46x109years, the sample will contain 2.0mg of uranium-238. What is the half-life of uranium-238?

  11. A sample contains 16mg of polonium-218. After 12 minutes the sample will contain 1.0mg of polonium-218. What is the half-life of polonium-210? • If you start with 2.97 x 1022 atoms of Molybdenum-91, how many atoms will remain after 62.0 minutes? The half-life of Mo-91 is 15.49 minutes.
