NUCLEAR FISSION/ NUCLEAR FUSION & its application to real life

Sort the following descriptions as either fission or fusion. FISSION "divide" splitting a nucleus radioactive waste radioactive decay chain reactions creates electricity in a nuclear power plant neutrons FUSION combining 2 small nuclei occurs in the sun hydrogen to helium "fusing" lacks technology to create totally clean energy The type of nuclear energy that produces radioactive wastes. nuclear fission nuclear fusion An ongoing series of fission reactions. chain reaction chemical reaction physical reacation Nuclear reactions that combine two small nuclei to make one large nucleus with a lot of energy. nuclear fission nuclear fusion Nuclear fission reactions result in _ . radioactive fusing radioactive decay The products of this reaction are not radioactive. fission fusion The reaction with the "u" in it. fusion fission The nuclear reaction with the "i" in it. fission fusion The nuclear reaction that sounds like "fuse." fission fusion Occurs only in the core of the sun. fission fusion The nuclear reaction that almost rhymes with "split." fission fusion What do nuclear fission and fusion have in common? Choose all that apply. (there are 2) produce large amounts of energy do not produce air polluion do not produce radioactive wastes Fast neutron therapy is used in modern medicine to treat cancer that is resistant to other methods of treatment. To produce the neutrons needed for fast neutron therapy, a stream of protons is accelerated towards a mass of beryllium. This causes the beryllium atoms to be split and to release neutrons from their nuclei.The methods used to perform fast neutron therapy are an example of which type of reaction? Fusion Fission Scientists have continuously been searching for ways to create a system for energy production through fusion reactions but have been unsuccessful. Which of the following explains why it is still not a practical source of power? Fusion reactions have virtually little to not risk of nuclear accidents. Fusion requires a large amount of energy to force aomts to initially fuse together. What is a fission reaction? The process of splitting the nucleus of an atom. The process of combining nuclei to form a larger nucleus. What is a fusion reaction? The process of splitting the nucleus of an atom. The process of combining nuclei to form a larger nucleus. What types of reactions will produce radiation? Neither fission nor fusion reactions Both fission fusion reactions Choose the correct term that completes the passage below. This information can be found on slide 3 in the powerpoint. Nuclear fission splits atoms into two new atoms and goes through radioactive decay. A vast amount of energy is produced. A chain reaction is a series of fission reactions that is a process in producing energy. During nuclear fission, there is no air pollution produced. However, nuclear fission can be dangerous due to the use of harmful radioactive elements. When these elements are split, a loss of control is possible releasing harmful radiation. The energy in the Sun currently is provided by a process that combines two hydrogen atoms to form one helium atom. In a few billion years, the Sun will begin a process combining three helium atoms into one carbon atom. This will cause the sun to expand and cool to a red color becoming a red giant.What process will the Sun perform when it becomes a red giant? fusion fission To discover if a cancer has metastasized, (spread to other parts of the body) an oncologist (cancer doctor) might request a Positron-emission tomography (PET) scan be performed by a radiologist. The PET scanner detects gamma radiation (which results from the splitting of a radioactive element) emitting from a chemical injected into the patient.Based on the information above, what type of reaction is occurring when a PET scanner is used? fission fusion What sort of reaction has happened when a hydrogen-3 atom becomes a helium atom-3? chemical reaction nuclear reaction What does NOT happen when a nucleus splits? Nuclear fusion Radiation is released Two fissionable substances commonly used in nuclear reactors include: Uranium-239 and plutonium-235 Uranium-235 and plutonium-239 Chain reactions in nuclear reactors need the absorption of-- electrons neutrons What particles are given out when a uranium atom undergoes fission? neutrons protons The medical field uses radioactive materials in order to identify various problems in the human body. the radioactive materials are used in-- Positron Emissions Tomography (PET) Bone scans Radiation therapy All of the above Nuclear power plants produce electrical energy from the process of fission. One of the possible uses of this energy is-- Heating homes Powering automobiles Reducing insect pests
