When the nuclei are merged, the excess energy is released. Like fission, nuclear fusion can also transmute one element into another. For example, hydrogen nuclei fuse in stars to form the elementhelium. Fusion is also used to force together atomic nuclei to form the newest elements on the pe...
For one, nuclear energy in the coming decades will include not only nuclear fission—the type of reaction already driving nuclear power plants—but also the much more elusive nuclear fusion. If scientists can solve the remaining puzzle pieces behind these technologies, both nuclear fission and ...
nuclear fission:核裂变,又称核分裂,是指由重的原子核,主要是指铀核或钚核,分裂成两个或多个质量较小的原子的一种核反应形式。原子弹、裂变核电站或核能发电厂的能量来源就是核裂变。其中铀裂变在核电厂最常见,热中子轰击铀235原子后会放出2到4个中子,中子再去撞击其它铀235原子,从而形成链式...
Nuclear fusion is the opposite process, in which two light nuclei merge to form a heavier one, yielding energy because the combination is lighter than the sum of its parts. Atoms heavier than iron can undergo fission, while lighter ones can fuse. Nuclear power stations generate energy from fis...
Fission and fusion are two words that sound very much alike, but they're actually very different! In this lesson, find out what each one is and how they work to create nuclear energy. Create an account Table of Contents Atoms and Molecules Nuclear Fusion Nuclear Fission Fusion and Fission...
每日一词:核裂变与核聚变揭示了两种能量释放机制。在核裂变中,如铀-235的案例,当一个大原子核分裂成两个较小的核,如铷和铯,多余的质量以核结合能的形式转化为能量。这个过程在核电站中被利用,比如远古时期加蓬奥克洛的自然核裂变现象。相反,核聚变则是轻原子核合并的过程,如在太阳核心,氢...
Nuclear fission and nuclear fusion are reactions which convert matter into energy. Atomic bombs rely on fission reaction while hydrogen bomb uses fusion.
This chapter discusses nuclear fission, nuclear fusion, and geothermal energy in detail. Nuclear energy comes from energy incorporated in atomic nuclei at the time when they are born; it is used to hold them together called binding energy. Of the nuclei of the periodic table, those at the ...
