Beta- decay involves the conversion of a neutron into a proton and the release of an electron and an electron antineutrino.
Beta+ decay involves the conversion of a proton into a neutron, sometimes by K capture, and the release of a positron and an electron neutrino.
Fusion involves the combining of two relatively light nuclei into one.
Alpha decay and fission are somewhat related...
Fission involves the separation of one relatively heavy nucleus into two or more.
Alpha decay is fission wherein the split off nucleus is a helium nucleus.
Any of these processes can leave the nucleus or the electron cloud in an excited state. When it comes back down to ground state, a gamma (nucleus) or x-ray (electron cloud) photon is emitted. This usually occurs nearly instantaneously, within about 1 x 10-12 seconds, but sometimes, in what we call a metastable state, this return to ground state is delayed, occasionally for a long time.
What else can I help you with?
Is the helium nucleus a byproduct of fission?
Yes, but only if the nuclear disintegration is alpha decay. Alpha decay is only one mode of radioactive decay, and in alpha decay, a helium-4 nucleus (the alpha particle) will appear. Beta decay (two types) and spontaneous fission are also modes of radioactive decay, and different particles appear in those events.

In which of these processes is an element of matter changed into a completely different element a nuclear fission b nuclear fusion c alpha decay d all the above?
The process where an element of matter is changed into a completely different element is nuclear fission. In nuclear fission, a heavy nucleus splits into lighter nuclei, resulting in the formation of different elements. Nuclear fusion is the process where two light nuclei combine to form a heavier nucleus, while alpha decay is a type of radioactive decay where an alpha particle is emitted from a nucleus.
What type of radiation is emitted by thorium?
Thorium-232 is an alpha emitter; rarely decay by spontaneous fission or double beta decay are possible.
Which of the following processes alwyas decreases the number of protons by an even number 1 fusion 2 beta decay 3 alpha decay or 4 fission what is the correct answer?
not sure buh i thinkk its ionisation. if not lets kill my chem teacher....!!!!The radioactive process called "alpha emission" decreases the number of protons in a decaying atom by the even number 2.
Does the sun give energy to earth through fission fusion beta decay or alpha decay?
The source of the energy produced by the sun which gives energy to the earth is fusion. In stars like the sun, the net effect of fusion is that four protons fuse into one alpha particle, with the release of two positrons, two neutrinos (which changes two of the protons into neutrons), and energy, but several individual reactions are involved, depending on the mass of the star. For stars the size of the sun or smaller, the proton-proton chain dominates.

Which lists correctly orders nuclear reactions from most radioactive waste generated to least waste generated within a given period of time?
Fission reactions Fusion reactions Alpha decay Beta decay
Why is alpha decay generally found occurring in atoms with large nuclei while beta decay is usually associated with much lighter nuclei?
I believe it has to do with fusion and fission, as all radioactive isotopes want to be as stable as possible.
What kind of reaction can change one element into another?
Alpha decay is a kind of radioactive decay in which an alpha particle is emitted from an atom. An alpha particle consists of two protons and two neutrons. Therefore, when an atom of an element undergoes alpha decay, it loses two protons, which changes the atom from one element to another. This is because each different element is identified by the number of protons in its atomic nuclei.
What is the type of radioactive decay in which positive particles are given off?
Alpha decay is the type of radioactive decay in which positive particles, specifically alpha particles, are emitted. These alpha particles consist of two protons and two neutrons bound together, giving them a positive charge.
What is associated with a nucleus breaking down and emitting a helium nucleus?
nuclear fission, alpha decay
What type of radiation is emitted by thorium?
Thorium-232 is an alpha emitter; rarely decay by spontaneous fission or double beta decay are possible.
What kind of radiation is emitted in the following nuclear reaction?
Type your answer here... Alpha decay Nuclear fission
What type of radiation is released during the decay of californium?
Alpha particles and neutrons fron spontaneous fission
The opposite reaction to fusion is called?
Fission is the opposite reaction to fusion. Fission involves the splitting of a heavy atomic nucleus into lighter elements, releasing a large amount of energy in the process.
Is hydrogen hydrogen helium alpha decay?
No. Hydrogen atoms combining to form helium is nuclear fusion. Alpha decay is a process whereby a large atomic nucleus ejects a helium nucleus.
