PPT-Nuclear Fission and Nuclear Fusion

Enormous Energies Nuclear Fission Take a large atom and impact the nucleus with a particle Split the atom releasing high energy more high energy neutrons and two daughter nuclides Fission occurs only rarely in nature Alpha decay is much more common. Uma Lad. PHY 3305: Modern Physics. December 2, 2014. Outline. . Fission and fusion will be defined. . Examples of fission and fusion will be discussed. . Modern day applications of these reactions will be discussed. . I can draw a . model of nuclear fission.. I can . recognize a nuclear fission equation. .. I can . describe two applications for nuclear fission.. I can . draw a model of nuclear fusion. .. I can . recognize a nuclear fusion equation. Dubna. , Russia. Avazbek NASIROV. Joint Institute for Nuclear Research. Contents of talk. Short information about synthesis of superheavy elements . . in heavy ion collisions.. 2. Significance of nuclear reactions: . ~bombs and nuclear power. Nuclear fission. ~the separating of a nucleus of an atom.. This is the process used by nuclear power stations (when it is kept under control).. It is also the process of an atom bomb (when it is allowed to run uncontrolled). . Heavy Elements can reduce. energy (i.e. increase binding. energy per nucleon) by. splitting roughly in half.. U 235 fission fragment distribution. Excess Neutrons. 235. 92. U + n . →. . 86. 38. Atoms consist of a nucleus surrounded by electrons. Chemistry is produced by interactions involving the electrons around the atom. t. his involves small energy changes (~0.01 eV) and can happen at room temperatures. Presentation by Claire, Elesha, Fatima, Juhee and Lala. Knowledge Framework vs. Knowledge Structure. . Knowledge Framework (KF). Knowledge Structure (KS). . Way to organize knowledge so students can learn the language: “to learn through language and to learn about language”. Large nuclei split into 2 smaller more stable nuclei. Sometimes natural. Most of the time extra energy is needed. Usually neutrons are released . Released neutrons may then hit other nuclei causing a . http://videos.howstuffworks.com/discovery/41267-powering-the-future-fusion-video.htm. 10 facts about NUCLEAR FUSION. 1. Nuclear Fusion is the joining of two atomic nuclei of smaller masses to form a single nucleus of larger mass.. Elements are Formed in Different Ways in our Universe. Nucleosynthesis. Nucleosynthesis. is the process of element (nuclei) formation.. Three types: . Big Bang nucleosynthesis. . Stellar (star) nucleosynthesis. Nuclear Reactions , Transmutations , Fission and Fusion Nuclear reactions The first induced nuclear reaction was accomplished by none other than Australian physicist Ernest Rutherford, the same guy 1. Which of the following statements are characteristic of an alpha particle? I. It is positively charged. II. It has no mass or charge. III. It's symbol is 0 -1 e. IV. It has poor penetrating ability Fission. Fusion. Transmutation. Skills to Master. HW . 20e. Read. OER . 20.4.
