1 Fission vs. Fusion Atom Review Jeopardy

2 Warm - Up Write the accomplishment of the scientists listed below
Democritus Dalton Thomson Millikan Rutherford Bohr Schrodinger

3 Objective Today I will be able to:
Distinguish between different types of radiation with respect to their penetration power. Complete a Venn Diagram to compare and contrast nuclear fission and fusion. Apply concepts about the atom to reviewing for an exam

4 Homework Study for the Exam Thursday

5 Agenda Warm – Up Personal Radiation Half-Life Problems
Fission vs. Fusion Notes Fission vs. Fusion Venn Diagram Review Questions? Exit Ticket

6 Task: Calculate your radiation exposure

9 What does your radiation exposure value mean?
No evidence of cancer occurring <10,000 mrem exposure Body has time to repair cells when exposed to low concentrations of radiation Correlation has been found with cancer and radiation exposure >50,000 mrem

10 Half-Life Practice Problems
There are 3.29 g of iodine-126 remaining in a sample originally containing 26.3 g of iodine The half-life of iodine-126 is 13 days. How old is the sample?  A sample that originally contained 2.5 g of rubidium-87 now contains 1.25 g. The half-life of rubidium-87 is 6 x 1010 years. How old is the sample? Is this possible? Why or why not?

11 Nuclear Fission and Fusion Notes

12 Nuclear Fission Nuclear Fusion

13 Nuclear Fission A heavy nucleus splits into more stable nuclei of intermediate mass.

14 Atomic Bombs Atomic bombs are an example of Fission Reactions.
“Little boy” and “Fat man” were Atomic bombs made from fission reactions with uranium and plutonium respectively. A fission chain reaction is started and continues until the bomb destroys itself.

15 Little Boy and Fat Man

16 Nuclear Power Plants Uranium-235 undergoes nuclear fission and releases thermal (heat) energy. This turns water to steam which spins turbines. The turbines produce electrical energy. Nuclear waste is fuel rods with unreacted uranium and radioactive products of fission. Right now this waste is buried in waste management facilities, like Yucca Mountain.

18 Nuclear Fusion Low-mass nuclei combine to form a heavier, more stable nucleus.

19 Hydrogen Bombs Hydrogen bombs are an example of nuclear fusion.
Two isotopes of hydrogen, 2H and 3H, fuse together and produce a lot of energy in the process. H-bombs release significantly more energy than atomic bombs.

20 The Sun: Nuclear Fusion
+ + + Energy Four hydrogen nuclei (protons) Two beta particles (electrons) One helium nucleus

21 Release huge amounts of energy
Nuclear Fission Nuclear Fusion High temp and pressure are used to combine light atoms to make heavier atoms Ex: Fuels the sun and stars & Hydrogen Bombs A heavy atom splits into two or more lighter nuclei Ex: Atomic Bombs & Nuclear reactors Release huge amounts of energy Produce nuclear waste

22 Comparing Fission and Fusion

23 Atomic Structure Review Sheet
Complete the atomic structure review sheet at your desk. Mr. Klotz has an answer key that will be posted on his website

24 Exit Ticket Write down three questions that could be on the exam tomorrow. One in each category Atomic theory Scientists Radioactivity Trade with a partner and have them respond Check their answers

For each atom, in its natural state, the number of electrons and the number of protons is equal. This number may or may not be the same as the number.
