Radioactive Decay‚ Nuclear Fission and Nuclear Fusion When elements undergo radioactive decay the atoms of one element are changed into the atoms of another element when an alpha or beta particle is emitted from an unstable nucleus. When a nucleus disintegrates and emits an alpha particle it is alpha decay‚ the alpha particle emitted contains two protons and two neutrons which is equivalent to a helium nucleus being released. Alpha decay occurs because there are too many protons‚ which causes

In nuclear chemistry‚ nuclear fusion and nuclear fission are different types of reactions that release energy due to the presence of high-powered atomic bonds between particles found within a nucleus. In fission‚ an atom is split into two or smaller‚ lighter atoms. Fusion‚ in contrast‚ occurs when two or smaller atoms fuse together‚ creating a larger and heavier atom. In both reactions‚ large amounts of energy are produced‚ with the only difference that fusion generates three or four times more energy

Nuclear Fission v. Nuclear Fusion Similarities DIfferences Both fission and fusion generate energy. During both processes neutrons are released. Both processes create elements with a lesser mass. Both fusion and fission processes are capable of creating a nuclear bomb. Nuclear Fission When large unstable nuclei decompose into smaller stable nuclei. Produces a lot of radioactive particles. Nuclear Fusion A nuclear reaction when a larger nucleus forms when the nuclei of two atoms fuse together

Describe and Evaluate the Use of Nuclear Fusion and Fission Atoms contain large amounts of energy with the ability to be released in two ways. One of these ways is to join Nuclei together in a process called nuclear fusion and another way is to split atomic nuclei in a process called nuclear fission. Though there are many arguments in favour and against both‚ nuclear fission currently holds the upper hand as a nuclear fusion reactor is yet to be formed. Nuclear fission occurs when a stable isotope

which is the foundation of nuclear science. Fission and fusion involves the dispersal and combination of elemental nucleus and isotopes‚ and part of nuclear science is to understand the process behind this phenomenon. Adding up the individual masses of each of these subatomic particles of any given element will always give you a greater mass than the mass of the nucleus as a whole. The missing idea in this observation is the concept called nuclear binding energy. Nuclear binding energy is the energy

probably do it. But Nuclear Fusion‚ unlike its cousin‚ Nuclear Fission‚ is quite difficult to achieve. Nuclear fission is the process of splitting large atoms‚ usually Uranium 235‚ to produce massive amounts of energy. The process enacted within all nuclear power plants is Nuclear Fission. Nuclear Fusion‚ on the other hand‚ is the exact opposite; Taking small atoms such as Hydrogen and pushing them together to build larger atoms. In theory‚ fusion produces more energy than fission in a mass-energy ratio

Nuclear fission is a atomic reaction that happens in the core of stars‚ mostly converting hydrogen to helium‚ but it requires a lot of energy. Nuclear burning is

Fusion as a future energy source Creating Nuclear Fusion could be a break through in finding an alternative source of energy. As of today we do not have the technology to make a nuclear fusion reactor‚ but we could be relying on them for power sometime in the next 30 to 40 years. Nuclear Fusion is created by forcing deuterium (D) and tritium (T) together‚ when forced together their nuclei fuse and then break apart to form a helium nucleus and an uncharged neutron. Most of the excess energy

that they had found a way to create nuclear fusion in a relatively simple and cheap way. Superhot fusion is the process in which deuterium‚ a heavier form of hydrogen‚ is held within a magnetic field and heated to tens of millions of degrees. The nuclei of the atoms fuse‚ and heat energy is released. This kind of fusion happens in our solar system’s sun. This type of fusion is known to occur‚ but recreating it is extremely difficult. One method of creating fusion failed because even a 100 trillion

observing its spectrum‚ due to the fact that different elements absorb and emit different wavelengths of light. (2) Gamow thought that nuclear fusions took place in the first minutes after the Big Bang‚ because he assumed that the initial components of the universe would have been seperate protons‚ neutrons and electrons. He hoped that they could build bigger atoms by fusion in the heat of the Big Bang‚ because nucleosynthesis‚ which
