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.

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. Links are provided below to Related questions that will help you sort this out.
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?
All the above
The two processes which produce nuclear changes are?
Fission & Fusion. I JUST now got an answer right by using this. Good Luck! :D Hope this was helpful.
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 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 is the type of radioactive decay in which positive particles are given off?
It's called alpha-decay. The two protons and two neutrons are removed in the form of alpha particles, or helium nuclei.
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 radiation is emitted in the following nuclear reaction?
Type your answer here... Alpha decay Nuclear fission
What kind of reaction can change one element into another?
There are only 2 ways that can happen, fission or fusion. Fusion is when two atoms combine to become a larger atom (almost exclusively two hydrogen atoms becoming 1 helium atom). Fission is much more common and is present in all radioactive elements.
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 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 type of radiation is released during the decay of californium?
Alpha particles and neutrons fron spontaneous fission
Is nuclear energy a fission or fusion reaction?
Nuclear energy is either:fission reaction, orfusion reaction, orradioactive decay
