Nuclear Reaction Sun

The nuclear reaction that takes place within the sun which is for all intents and purposes a giant nuclear fusion reactor is the fusion of two isotopes of hydrogen deuterium 12 h and tritium 13 h into a nucleus of helium 4 24 he containing two electrons orbiting a nucleus of two protons and two neutronsthe reaction is as follows.

Nuclear medicine nursing responsibilities soviet union order 227. In nuclear physics and nuclear chemistry a nuclear reaction is semantically considered to be the process in which two nuclei or a nucleus and an external subatomic particle collide to produce one or more new nuclidesthus a nuclear reaction must cause a transformation of at least one nuclide to another. Select all that apply. During a nuclear reaction such as a fission or fusion reaction.

Generate heat absorb a lot of energy fuse atoms of hydrogen to make helium atoms generate light 2 see answers guruaher3 guruaher3 answer. Every second the sun fuses 620 billion kg of hydrogen nuclei protons into helium to produce 3846 trillion trillion joules of energy per secondthis is equivalent to the energy released in the explosion of 9192 billion megatons of tnt per second. The fusion of deuterium and tritium nuclei is accompanied by a loss of approximately 00188 amu of mass which is completely converted into energy.

Because this chain of reactions starts with two hydrogen nuclei that is two single protons it is called the proton proton chainin step 1 two protons collide and fuse forming deuterium which is designated 2 h or d. The energy from the sun both heat and light energy originates from a nuclear fusion process that is occurring inside the core of the sunthe specific type of fusion that occurs inside of the sun is known as proton proton fusion. Two additional particles are released.

Nuclear reactions in the sun core 15 million o k photosphere visible surface 5700 o k photons no longer collide can escape chromosphere 10000 o k corona 2 million o k low density but high temperature due to magnetic fields and violent convective motions of lower layers source of x rays. A positron and a neutrino. Sun the ultimate nuclear fusion reactor.

Inside the sun this process begins with protons which is simply a lone hydrogen nucleus and through a series of steps these protons fuse together and are. A nuclear reaction is considered to be the process in which two nuclear particles two nuclei or a nucleus and a nucleon interact to produce two or more nuclear particles or rays thus a nuclear reaction must cause a transformation of at least one nuclide to another. If a nucleus interacts with another nucleus or particle and they then separate without.

Sometimes if a nucleus interacts with another nucleus or particle without changing the nature of any nuclide the process. Such fusion reactions occur at the core of the sun and other stars.
