Presentation Transcript

  1. Draw a helium atom showing location of number and charge or major components. • How is picture of a model • Like and actual atom • Unlike • What sticks the nucleus together, what is the roll of neutrons • What element would be made if helium captured another neutron • What element would be made if this atom emitted a beta particle and a neutron became a proton in the nucleus?

  2. What is an alpha particle and what is its charge? • Why does it fly away from the nucleus it comes from • What does 018 become when it radiates an alpha particle? • Use the periodic table to say • Why Radon is a gas • Uranium is a metal • Iodine is a non metal

  3. How do radioactive elements form compounds?

  4. When Uranium combusts it forms U3O8 • Write a word equation • Write a balanced equation • What is conserved in this reaction? Why?

  5. Name this compound UO2(CO3) • What is the reaction name when it is heated • What is the word equation • Write a balanced equation

  6. Search “uranium precipitation” • Why is this important for waste dumps • What is precipitation

  7. What is biotic and abiotic? • All living things respire why? • What is the word equation? • Plants photosynthesize what does this mean? • How is energy drawn in a food web?

  8. Google the half life or C14 Why are all living things radioactive? Why do fossil fuels contain no C14? If C14 levels are falling how does it prove Human activity is causing increase in Greenhouse gases.

  9. Google carbon cycle • In carbon footprint why use the word footprint • How can we reduce our use of Fossil fuels? • Is nuclear energy renewable? • What are some of the effects of Climate change on Ecosystems.

  10. http://www.youtube.com/watch?v=QsB83fAtNQE&feature=related • In this clip what are the light and sound waves • What is the difference between a transverse and longitudinal wave
