Question 1 1. The type of fusion occurring in stars is dependent on two variables. The first is mass, since that determines the magnitude of the temperature and pressure at the star's interior. What is the second?

Question 2 2. The charges on beta particles (Β - ), alpha particles (α) and gamma (γ) rays are _____ respectively.

Question 3 3. In alpha decay, an atom radiates by ejecting two neutrons and two protons. In beta decay, an atom radiates by ejecting either an electron or a positron. What does an atom eject to radiate with gamma decay?

Question 4 4. Which type of reaction is involved with nuclear reactors?

Question 5 5. How does a nuclear reaction differ from a chemical reaction?

Question 6 6. The majority of nuclear fusion occurring in our Sun has two hydrogen atoms fusing together to form a helium-4 atom. What is this process known as?

Question 7 7. Radiation can be defined as the transmission of energy from a body in the form of what?

Question 8 8. Which particles are present in the nucleus of an atom?

Question 9 9. It is harder to break apart a nucleus with _____ energy than a nucleus with _____ energy.

Question 10 10. Fission of uranium-235 nuclei can produce _____ and other product isotopes.

Question 11 11. What is the difference between ionizing and non-ionizing radiation?

Question 12 12. Nuclear fission is the process in which _____ with the release of energy.

Question 13 13. For nuclear fusion to occur, very high temperatures and pressures are needed. The high pressure gets the atomic nuclei close enough to one another to fuse. What does high temperature do to allow the fusion process?

Question 14 14. In proton-proton fusion the final helium-4 atom weighs less than the original four hydrogen atoms that fused together. This excess mass was converted to energy. We can see the relation of mass to energy for this reaction in Einstein's famous equation E = mc^2, where 'E' is energy, 'm' is mass, and 'c' is the speed of light. Knowing all this, which of the following is true?

Question 15 15. In a hydrogen bomb, the fusion process is triggered by a nuclear fission reaction. What is the difference between nuclear fusion and nuclear fission?

Question 16 16. Nuclear binding energy can be defined as the amount of energy needed to break one _____ of nuclei into individual nucleons.

Question 17 17. Which cause of radiation is capable of producing both non-ionizing and ionizing radiation?

Question 18 18. Nuclear power plants utilize _____ to generate power.

Question 19 19. When does nuclear fusion occur?

Question 20 20. Radiation is capable of causing severe health effects. What do you need to be concerned with for determining the severity of the health effects caused by exposure to radiation?
