What happens when an element decays through alpha decay and spontaneous fission?
In alpha decay decay two neutrons and two protons are released from the nucleus and an alpha particle (an Helium nucleus) is released: the atom's nucleus changes in to that of a nucleus two place earlier in the periodic table (Proton number falls by 2, Nucleon number falls by 4) In spontaneous fission a heavy, unstable nucleus autonomously disintegrates and falls in to two smaller nuclei (daughter nuclei) of a similar mass and a few (depending on the nature of the fission) neutrons are released with high kinetic energy.
Is spontaneous fusion a form of radioactive decay?
No, the fusion process is the opposite of the radioactive decay process. Fusion is the merging together of nuclei to form a heavier nucleus whereas fission or radioactive decay is the splitting apart of a heavy nucleus into lighter daughter nuclei.
What is the process in which a heavy nucleus divides to form smaller nuclei one or two neutrons and a large amount of energy?
radioactive decay
What do heavy nuclei emit when they decay?
The question cannot be definitively answered from the information given. It depends on the isotope what the decay modes are. Brookhaven National Labs has an interactive chart of nuclides; you can click on a particular isotope and see the half-life and decay modes. I've put a link to it in the Related Links section.
What is it called when atomic nuclei spontaneously decay?
How the nucleus decays depends on the particular isotope. Some even decay in more than one way. One possibility is called alpha decay. In alpha decay, the nucleus emits an alpha particle (two protons and two neutrons). Another possibility is beta decay, in which one of the nucleons changes from a neutron to a proton or vice versa and the nucleus will throw out a beta particle. A beta particle can be either an electron or a positron. (To conserve lepton number, the nucleus also emits an electron antineutrino or an electron neutrino at the same time.) A third case is electron capture. In this, one of the inner electrons is absorbed by the nucleus, a proton changes to a neutron, and an electron neutrino is thrown off. Heavy nuclides can undergo spontaneous fission, in which the nucleus splits into two smaller daughter particles with mass numbers of roughly 90-100 and 130-140. Often some spare neutrons are also ejected at the same time. Cluster decay is yet another mode, which happens only for nuclei which also decay via alpha decay. It's similar to alpha decay except the emitted particle is not a helium-4 nucleus but a heavier element. It's distinguished from spontaneous fission by the fact in cluster decay, only certain nuclei are emitted and they're always well under 90 amu. Other rare decay modes are possible: proton emission, neutron emission, double proton emission, double beta decay, double electron capture, double positron emission, and electron capture with positron emission. Most of these names should be self-explanatory.
How are elements artificially transmuted?
Scientists can bombard atomic nuclei with high-energy particles such as protons, neutrons, or alpha particles. Scientists synthesize a transuranium element by the artificial transmutation of a lighter element. ... It involves nuclear change, not chemical change. NOTE nuclear decay is a transmutation that happens naturally
Alpha decay results in the formation of a new element with the atomic number?
That's a very vague question, but if it's the theory you're after;If a nucleus is heavy (>82 protons, generally at A2 level) it will emit an alpha particle. For example,238U --> 234Th + 4α + 0νe_92______76___ 2___0In this emission, Uranium-238 is the parent nucleus. It emits an alpha particle, which has 2 protons and 2 neutrons. Thallium-234 is the daughter nucleus. The other thing is a neutrino. It is a lepton, and is there to balance the lepton number.Apologies for the big black line, but it's the only way I could get wikians to play nicely.
When the nuclei of heavy atoms with many protons are split this process is called?
Generally this is called nuclear fission. In the special case where one of the new particles produced is a Helium-4 nucleus (2 protons, 2 neutrons) the process is radioactive decay and specifically alpha emission. (The He-4 nucleus is called an alpha particle, as it was the first such particle recognized. A beta particle is an electron emitted from the nucleus with the conversion of a neutron to a proton = beta emission.)
What is the origin of nuclear energy?
There are two major types of nuclear energy, fusion and fission. Fusion comes from hydrogen nuclei sticking together in the hearts of stars, which liberates energy. Fission energy comes from the splitting of heavy nuclei. A third type of nuclear energy comes from the slow decay of unstable isotopes, most generally through the release of alpha or beta particles. Both of these are the result of a transmutation of the isotope. Fissionable isotopes are produced naturally in supernova.
Which radiation is the slowest out of alpha beta and gamma?
Alpha particles are heavy doubly ionized helium nuclei. Beta particles are nuclear electrons. Gamma are extremely short photons with zero rest mass. Hence obviously, Speed of Gamma>Beta>Alpha.
What is the name of the nuclear process in which heavy nuclei split into two lighter nuclei?
Fission
